SUMMARY

Follow-up to #42053, which upgraded ColorPickerControl (custom presets, resolveThemeTokens, outputFormat) and used it to fix ConditionalFormattingControl. This PR finds and fixes the four remaining places in the app that still used a legacy/degraded color-selection UI instead of the shared picker, one commit per item.

1. Gauge chart interval colors

Gauge/controlPanel.tsx's "Interval colors" control asked users to type comma-separated 1-indexed positions into the chosen color scheme (e.g. 1,2,4), with zero visual feedback and silent discarding of malformed input.

Replaced with IntervalColorsControl: one ColorPickerControl per interval bound (parsed from the existing intervals control), storing real hex colors in a new interval_colors field, positionally matched to those bounds.

Design decision: bounds stay owned by the existing intervals text control rather than being folded into the new control's own row list (which the row-list add/remove pattern in the task brief technically implied). This keeps a single source of truth for bounds and avoids needing two-way sync between two independent controls — the new control's row count simply tracks whatever intervals currently contains.

Backward compatibility: charts saved before this control existed only have interval_color_indices (the old index strings). getIntervalBoundsAndColors in transformProps.ts still resolves those indices against the categorical scheme at render time whenever interval_colors is empty, so existing dashboards render identically with no migration. The control also resolves legacy indices to real colors for display the first time such a chart's panel is reopened (editor convenience only, not required for correct rendering).

Gauge: new Interval colors control + rendered chart

2. Bullet chart band colors

Bullet chart background bands were hardcoded to a 4-step theme-token ramp with no color control at all — a genuinely new feature, not a swap.

Added an optional range_colors control (BulletRangeColorsControl): one ColorPickerControl per threshold parsed from the existing ranges control, each starting unset ("use default") with a "Use default" link to clear a customization. transformProps.ts captures each range's chosen color by its original (pre-sort) position in ranges before the existing largest-first band sort reorders them for nested drawing, so colors stay pinned to the correct threshold regardless of draw order.

Backward compatible by construction: range_colors is optional and defaults to empty, so charts saved before this control existed have no such field and keep rendering with the exact default ramp.

Bullet: new Range colors control + rendered chart with custom band colors

3. Big Number Period-over-Period comparison colors

The comparison-color control was a 2-choice SelectControl ("Green for increase, red for decrease" / reverse) bound directly to theme.colorSuccess/theme.colorError.

Replaced with two ColorPickerControls, increase_color / decrease_color, using the exact resolveThemeTokens + outputFormat="hex" pattern #42053 introduced: picking the Green/Red preset swatch stores the token name (so it still reads the same as before for users who just want the classic behavior), while any other pick stores a literal hex color. Exported SPECIAL_COLORS/SpecialColorKey from ColorPickerControl.tsx so this call site doesn't redefine the Green/Red mapping.

The color→style resolution moved into two small, independently unit-tested pure functions in utils.ts (resolveComparisonColorKeys, getComparisonColorTokens) rather than living inline in PopKPI's render body — jsdom doesn't reliably expose emotion's injected styles to toHaveStyle for direct component assertions, so the logic needed to be testable on its own.

Backward compatibility: resolveComparisonColorKeys falls back to the legacy comparisonColorScheme field (kept, @deprecated in types.ts) whenever the new fields are absent — including correctly reversing increase/decrease for charts saved with the old "Red for increase, green for decrease" choice, the case a naive default-to-Green migration would have silently broken.

Big Number PoP: new Color for increase/decrease pickers + rendered comparison

4. Admin Theme editor curated colors

ThemeModal.tsx only exposed antd theming as a single JSON textarea, requiring admins to paste in a whole token object from an external tool to change even one color.

Added a "Colors" section (ThemeColorPickers) above the JSON textarea with one ColorPickerControl per curated antd token — the 5 SEED colors (colorPrimary, colorSuccess, colorWarning, colorError, colorInfo) plus 6 load-bearing map/alias tokens (colorLink, colorText, colorTextSecondary, colorBgBase, colorBgContainer, colorBorder). This intentionally does not attempt the full 100+ token surface — everything else stays fully editable via the JSON textarea, which remains the source of truth. Names are taken directly from antd's own SeedToken/MapToken types, not invented.

Sync is two-way, via two small pure functions (tryParseThemeJson, patchThemeJsonToken):

  • Picker → JSON: patches just that key into the JSON's token object and re-serializes with the modal's existing 2-space indent, preserving every other key (curated or not).
  • JSON → pickers: each render re-parses the textarea's current value and re-derives picker values from it.
  • Invalid/mid-edit JSON: tryParseThemeJson returns null instead of throwing (matching the file's existing isValidJson convention); the section shows a small notice and pickers stop persisting edits until the JSON is valid again.

The section is hidden for read-only system themes, matching the existing Format/Apply button visibility.

No backward-compat concern — additive UI over the same JSON, nothing about existing saved themes changes.

Theme editor: curated Colors section synced from JSON

  • npm run test in superset-frontend/ — new/updated suites:
    • plugins/plugin-chart-echarts/test/Gauge/transformProps.test.ts
    • src/explore/components/controls/IntervalColorsControl/IntervalColorsControl.test.tsx
    • plugins/plugin-chart-echarts/test/Bullet/transformProps.test.ts

    • plugins/plugin-chart-echarts/src/BigNumber/BigNumberPeriodOverPeriod/{utils,PopKPI}.test.tsx
    • src/features/themes/{ThemeModal,ThemeColorPickers}.test.tsx
  • Manually: create/edit a Gauge chart, expand Customize → Intervals; create/edit a Bullet chart, expand Customize → Range colors; create/edit a Big Number w/ Time Comparison chart with "Add color for positive/negative change" enabled; open Settings → Themes → + Theme.
  • Backward compatibility: open an existing Gauge chart saved with interval_color_indices only, an existing Bullet chart with no range_colors, and a Big Number PoP chart saved with only comparison_color_scheme (including the Red value) — all three should render identically to before this PR.

Nice consolidation, and the one-commit-per-item structure keeps it bisectable with real backward-compat handling on each swap (legacy interval_color_indices / comparison_color_scheme fallbacks, additive optional fields). One process question: this bundles four unrelated areas (Gauge, Bullet, Big Number PoP, Theme editor), each with its own new control dir and backward-compat surface — might be worth confirming maintainers are fine reviewing it as a single PR vs splitting per area. Minor: ThemeColorPickers re-parses the JSON textarea on each render (the useMemo keyed on jsonData mitigates it).

Heya @sha174n, thanks for the read-through! Given each swap already lands as its own bisectable commit with its own backward-compat handling, I'm inclined to keep this bundled rather than split it four ways at this point. Happy to reconsider if another maintainer feels strongly about it.

And yeah, the useMemo already covers the re-parse cost, as you noted.

  • superset-frontend/plugins/plugin-chart-echarts/src/BigNumber/BigNumberPeriodOverPeriod/PopKPI.tsx - 1
    • Duplicated color resolution · Line 188-192
      The `colorValue` selection (`percentDifferenceNumber > 0 ? resolvedIncreaseColor : resolvedDecreaseColor`) plus `getComparisonColorTokens` is duplicated in `getArrowIndicatorColor` and the `useMemo`. If the sign logic changes in one place, arrow and pill colors diverge. Consider extracting one shared helper.
  • superset-frontend/plugins/plugin-chart-echarts/src/Gauge/types.ts - 1
    • Deprecated tag on required field · Line 53-59
      `intervalColorIndices` is still a required property and is still actively read as the legacy fallback in `getIntervalBoundsAndColors` and `controlPanel.tsx`. Marking a required, still-used field `@deprecated` is contradictory: IDEs will strikethrough and warn on every legitimate usage, and it implies the field can be removed when it cannot. Consider dropping the tag or making the field optional.
  • superset-frontend/src/features/themes/ThemeColorPickers.tsx - 1
    • Unused disabled prop · Line 125-125
      The `disabled` prop is declared, defaulted, and checked in `handleTokenChange`, but the only consumer (`ThemeModal` line 504) renders `` without it and hides the whole Colors section when read-only. This is dead API surface introduced by the diff. Wire it up or drop it.
  • superset-frontend/src/features/themes/ThemeColorPickers.test.tsx - 1
    • Brittle antd-internal test · Line 148-183
      This interaction test depends on antd ColorPicker internal DOM classes (`.ant-color-picker-trigger`, `.ant-color-picker-input input`) and internal event behavior (typing hex + Enter firing `onChangeComplete`). The sibling `ColorPickerControl.test.tsx` explicitly avoids this, noting it "would require more complex mocking as it uses complex internal components." These internals aren't part of antd's public API and can change between versions, making the test brittle/flaky. Consider mocking `ColorPickerControl` to invoke `onChange` directly.
  • superset-frontend/src/explore/components/controls/IntervalColorsControl/IntervalColorsControl.test.tsx - 1
    • Test coupled to global default · Line 116-142
      This test asserts the picked preset is `#1f77b4`, but `IntervalColorsControl` never forwards `colorScheme` to `ColorPickerControl`, which builds presets from `getCategoricalSchemeRegistry().get()` (no key → global default `SUPERSET_DEFAULT`). The assertion only passes because `testScheme`'s first color coincidentally equals the default's. Set `testScheme` as default in `beforeAll` (as `ColorPickerControl.test.tsx` does) to make the test self-contained.
  • superset-frontend/src/explore/components/controls/IntervalColorsControl/index.tsx - 1
    • Type-only import · Line 25-25
      `IntervalColorsControlProps` is an interface used only as a type annotation (line 95), yet it is imported as a value while line 24 uses `import type` for the same kind of type-only import. Use `import type { IntervalColorsControlProps } from './types';` for consistency with the codebase's type-safety convention.
  • superset-frontend/plugins/plugin-chart-echarts/src/BigNumber/BigNumberPeriodOverPeriod/utils.ts - 1
    • Object injection via bracket notation · Line 153-153
      The use of bracket notation `themeColors[colorValue]` is flagged as a potential object injection sink (CWE-1321). Although `hasOwnProperty.call` is used to validate the key, the linter still flags the access. Consider using a `Map` instead of a plain object to avoid prototype pollution risks. Note: A similar issue exists at line 77 (unchanged code) for `comparisonFontSizesMapping[proportionValue]`.

  • superset-frontend/src/explore/components/controls/BulletRangeColorsControl/index.tsx - 1
    • Duplicated tokenize logic · Line 40-46
      `parseRanges` here is functionally identical to `tokenizeToNumericArray` in `plugin-chart-echarts/src/Bullet/utils.ts` (split → trim → filter empty → `Number` → `Number.isFinite`). The utils comment even says it must "match" this function. This PR's whole purpose is keeping them aligned, so divergence risk is real. Consider a single shared helper (or a shared test) to avoid silent color/band misalignment.
  • superset-frontend/plugins/plugin-chart-echarts/src/BigNumber/BigNumberPeriodOverPeriod/PopKPI.tsx - 1
    • Duplicated color-selection logic · Line 188-192
      The ternary `percentDifferenceNumber > 0 ? resolvedIncreaseColor : resolvedDecreaseColor` is duplicated verbatim in `getArrowIndicatorColor` (188-191) and inside the `useMemo` (206-209). If one is edited without the other, the arrow color and the pill background/text will diverge for the same metric sign. Consider extracting a single `getColorValue()` helper used by both.
  • superset-frontend/src/explore/components/controls/index.ts - 1
    • Missing control type union · Line 61-62
      These two new control types are registered in the control map but not added to the `InternalControlType` union in `packages/superset-ui-chart-controls/src/types.ts`. Control panels reference them as string literals (`type: 'IntervalColorsControl'` in Gauge, `type: 'BulletRangeColorsControl'` in Bullet), so they fall outside the typed union and lose type safety. Add both names to the union.
  • superset-frontend/src/explore/components/controls/IntervalColorsControl/index.tsx - 1
    • Legacy color logic diverges · Line 58-80
      `resolveLegacyColors` duplicates the fallback in `getIntervalBoundsAndColors` (transformProps.ts), which the comment on line 56 calls "equivalent" — but the two diverge. For legacy index 0, transformProps computes `(0-1) % len = -1` → `colors[-1]` (undefined) → falls back to `colorFn.colors[idx]`, while here `((0-1)%len+len)%len = len-1` yields the last scheme color. Empty-scheme handling also differs (`''` vs `undefined`). A chart with index 0 would render one color but show another in the panel. Consider sharing one helper.
  • superset-frontend/src/features/themes/ThemeColorPickers.tsx - 1
    • Unused disabled prop · Line 125-125
      `disabled` is never passed by the only consumer `ThemeModal` (line 639-642), and `ColorPickerControl` has no `disabled` prop, so the guard at line 139 is unreachable. Worse, a caller passing `disabled` would still see interactive pickers that silently drop `onChange`. Remove the prop or forward it to `ColorPickerControl`.
  • superset-frontend/src/explore/components/controls/ColorPickerControl.tsx - 1
    • Unused exported symbols · Line 30-30
      `SPECIAL_COLORS` and `SpecialColorKey` are exported but never imported anywhere in the repo (grep across src/plugins/packages finds only this file). The intended consumer `BigNumberPeriodOverPeriod` uses `ColorSchemeEnum` from `@superset-ui/chart-controls` instead. Consider reverting these to module-private to avoid dead public API surface.
  • superset-frontend/plugins/plugin-chart-echarts/src/Gauge/types.ts - 1
    • Doc contradicts precedence logic · Line 61-66
      The JSDoc says `intervalColors` "Takes precedence over `intervalColorIndices` when present", but `getIntervalBoundsAndColors` (transformProps.ts:76) only prefers it when `Array.isArray(intervalColors) && intervalColors.length > 0`. Since `DEFAULT_FORM_DATA` sets `intervalColors: []`, an empty array is present yet falls back to legacy indices. Consider wording the doc to match the non-empty guard.

rusackas force-pushed the feat/color-picker-consolidation branch from 5ec5ad2 to 3d4241f Compare September 21, 2026 16:53
claude and others added 19 commits October 2, 2026 07:33
The Bullet chart's background range bands were hardcoded to a 4-step
theme-token ramp (colorFillQuaternary -> colorFill) with no way to
customize them, unlike the rest of the chart (ranges, markers, marker
lines) which are all user-configurable.

Add an optional `range_colors` control (BulletRangeColorsControl) that
renders one ColorPickerControl per threshold parsed from the existing
`ranges` control. Each row starts unset ("use default") with a "Use
default" link to clear a customization once made; unset rows keep
using the theme-token ramp exactly as before.

`Bullet/transformProps.ts` captures each range's chosen color
(matched by its original, pre-sort position in `ranges`) before the
existing largest-first band sort reorders them for nested drawing, so
colors stay pinned to the correct threshold regardless of draw order.

Backward compatible by construction: `range_colors` is optional and
defaults to empty, so Bullet charts saved before this control existed
have no such field and render with the exact same default ramp.
The Period-over-Period Big Number's "color scheme for comparison"
control only offered two fixed choices ("Green for increase, red for
decrease" and its reverse), bound directly to theme.colorSuccess /
theme.colorError with no room for a brand-specific color.

Replace it with two ColorPickerControls, `increase_color` and
`decrease_color` (defaulting to the 'Green' / 'Red' semantic tokens,
matching the historical default), using the same resolveThemeTokens +
outputFormat="hex" pattern #42053 introduced for
FormattingPopoverContent: picking the "Green"/"Red" preset swatch
stores the token name (so the UI still reads the same as before for
users who just want the classic behavior), while any other pick stores
a literal hex color.

`increaseColor`/`decreaseColor` and the color->style resolution move
to two small, independently unit-tested pure functions in utils.ts
(`resolveComparisonColorKeys`, `getComparisonColorTokens`) rather than
living inline in PopKPI's render body, since jsdom doesn't reliably
expose emotion's injected styles to `toHaveStyle` for direct
component-level assertions.

Backward compatibility: `resolveComparisonColorKeys` falls back to the
legacy `comparisonColorScheme` field (still read, marked @deprecated in
types.ts) whenever the new fields are absent, including correctly
reversing increase/decrease for charts saved with the old "Red for
increase, green for decrease" choice -- the case a naive
default-to-Green migration would have silently broken.

Also exports `SPECIAL_COLORS/SpecialColorKey` from ColorPickerControl
so other call sites (like this one) don't need to redefine the
Green/Red semantic color mapping.
The admin Theme editor (ThemeModal) only exposed antd theming as a
single JSON textarea, requiring admins to paste in a whole token
object generated by an external tool just to change, say, the brand
color.

Add a "Colors" section (ThemeColorPickers) above the JSON textarea
with one ColorPickerControl per curated antd token: the 5 SEED colors
(colorPrimary, colorSuccess, colorWarning, colorError, colorInfo) plus
6 load-bearing map/alias tokens (colorLink, colorText,
colorTextSecondary, colorBgBase, colorBgContainer, colorBorder). This
intentionally does not attempt to cover the full 100+ token surface --
anything else stays fully editable via the JSON textarea, which
remains the source of truth. Token names are taken directly from
antd's own SeedToken/MapToken types, not invented.

Sync is two-way and implemented as two small, independently tested
pure functions (`tryParseThemeJson`, `patchThemeJsonToken`):
- Picker -> JSON: patches just that one key into the JSON's `token`
  object and re-serializes with the same 2-space indent used
  elsewhere in this modal, preserving every other key (curated or
  not) and their values.
- JSON -> pickers: each render re-parses the JSON textarea's current
  value and re-derives picker values from it, so typing in the
  textarea updates the matching swatches live.
- Invalid/mid-edit JSON: `tryParseThemeJson` returns null instead of
  throwing (matching the file's existing `isValidJson` convention);
  the section shows a small notice and pickers stop persisting edits
  until the JSON is valid again, rather than crashing or silently
  clobbering the textarea.

The section is hidden for read-only system themes, matching the
existing Format/Apply button visibility, and both directions of sync,
invalid-JSON handling, and "uncurated token survives a picker edit"
are covered in ThemeColorPickers.test.tsx (unit) and ThemeModal.test.tsx
(integration).
- Drop the static default on increase_color/decrease_color so the legacy
  comparison_color_scheme fallback in resolveComparisonColorKeys still
  applies to old dashboards instead of getting preempted by
  applyDefaultFormData.
- Read the legacy interval_color_indices field from form_data instead of
  state.controls in Gauge's IntervalColorsControl mapStateToProps, since
  it's no longer a registered control.
- Resolve theme token names and strip pre-existing hex alpha before tinting
  in getComparisonColorTokens, so it stays valid CSS for both.

…ange colors

tokenizeToNumericArray only dropped NaN, so a range value overflowing to
Infinity survived while BulletRangeColorsControl's own parser (which
sets up one color row per range) already dropped it -- shifting later
range_colors entries onto the wrong band. Filter on Number.isFinite in
both places so the two stay index-aligned.

Also reject a non-object `token` in ThemeColorPickers' tryParseThemeJson;
patchThemeJsonToken spreads it, so a malformed `token` (a string or
array) was silently rewritten into numeric-keyed junk on the next picker
edit instead of surfacing the existing invalid-JSON notice.

userEvent.type() parses `{` and `[` as key descriptors, so typing raw
JSON into the textarea throws before the assertion runs. Use the same
clear-then-paste pattern the file's helpers already rely on.

…eme pickers on invalid JSON

- PopKPI: hoist a single `comparisonColorValue` shared by the arrow
  indicator and the pill background/text so they cannot diverge.
- BigNumberPeriodOverPeriod controlPanel: extract a shared
  `comparisonColorControlConfig` spread into both `increase_color` and
  `decrease_color`, leaving only label/description per control.
- ColorPickerControl: add a `disabled` prop passed through to the antd
  ColorPicker.
- ThemeColorPickers: disable the pickers when the theme JSON is invalid
  or the editor is read-only, so the UI matches the dropped-edit
  behaviour, and cover it in tests.

Two bito findings:
- BulletRangeColorsControl's parseRanges duplicated
  tokenizeToNumericArray in Bullet/utils.ts, the exact split/trim/
  Number/isFinite pipeline already flagged once in this PR as needing
  to stay in sync (colors are matched positionally against it). Now
  imports the shared function instead of reimplementing it.
- PopKPI's down-arrow test asserted the arrow but never the
  valueDifference text next to it, so a regression dropping the delta
  would still pass.

…olors

Extract the shared row layout and color-array-update logic used by
IntervalColorsControl and BulletRangeColorsControl into
controls/shared/RangeColorRow.tsx. Guard getComparisonColorTokens'
alpha-tint suffix so it's only applied to 6/8-digit hex colors, leaving
non-hex theme tokens (e.g. an rgba() value) passed through unchanged
instead of producing invalid CSS. Replace a misleading jsdom-coverage
comment in PopKPI.test.tsx with a real @emotion/jest toHaveStyleRule
assertion on the arrow indicator's resolved color.

…heck

emotion's css prop styles aren't reliably observable through jsdom's
computed styles here; the toHaveStyleRule assertion added in the prior
commit fails in CI ("Property not found: color") even though the
underlying color-resolution logic is correct and already covered by
direct unit tests in utils.test.ts.

Addresses review feedback on the color-picker consolidation:
- Migrate comparison_color_scheme into increase_color/decrease_color, and
  interval_color_indices into interval_colors, in handleDeprecatedControls
  so the legacy value survives the first save instead of being dropped by
  getFormDataFromControls (which only serializes registered controls).
- Resolve a non-hex (rgb/rgba) comparison color into a real low-alpha
  background tint instead of reusing the same value for text and
  background, which made the comparison symbol invisible.
- Block BulletRangeColorsControl color edits while the ranges input has a
  blank token between two numbers (e.g. "20,,60"), which previously let an
  edit get positionally misaligned once the blank was filled back in.

…on edit

The Gauge interval-colors control's original description ("Comma-separated
color picks for the intervals...") was superseded by the current
IntervalColorsControl wording without re-running babel_update.sh, leaving
the old string in messages.pot with no corresponding source reference.
Verified against a fresh pybabel extraction: removing it leaves zero
missing/stale entries.

… and bullet range control

`resolveLegacyIntervalColors` fell back to the registry's default scheme
when an explicit color_scheme name was unregistered, instead of leaving
colors unresolved; and used the bound's absolute position instead of a
counter for bounds missing an explicit legacy index, misassigning colors
whenever only some bounds had one. Also fixed a BulletRangeColorsControl
test asserting `toBeDisabled` on AntD's inner text <span> instead of the
actual <button> (jest-dom's matcher only recognizes form elements).

…ignment

IntervalColorsControl parsed `intervals` with the same lenient tokenizer
BulletRangeColorsControl uses, but never guarded against a transient
mid-edit value (e.g. "20,,60") the way Bullet's control does -- a color
edit made while the list was incomplete could permanently misalign once
the blank was filled back in. Reuse the existing `isRangesInputComplete`
guard and disable the picker until the bounds list is complete.

Also adds the test coverage bito-code-review flagged as missing for
`tokenizeToNumericArray`/`isRangesInputComplete`'s non-numeric,
non-finite, and blank-token-before-the-tolerated-trailing-one paths.

      The seven new tests declare `const formData: any` (lines 398, 409, 420, 432, 440, 452, 465), which violates the repo's "NO `any` types" standard in AGENTS.md and .cursor/rules/dev-standard.mdc; the pre-existing `eslint-disable-next-line @typescript-eslint/no-explicit-any` at line 31 shows this rule is enforced here. A local type alias for the legacy form-data shape (or exporting `FormData` from `src/explore/store`) keeps these tests typed.
  • superset-frontend/src/features/themes/ThemeModal.tsx - 2
    • Inconsistent readOnly guard · Line 637-644
      The new `Colors` block is fully unmounted when `isReadOnly` is true, so the `disabled` prop `ThemeColorPickers` already supports is never used here. The sibling JSON textarea at line 684 instead stays mounted with `readOnly={isReadOnly}`. Prefer passing `disabled={isReadOnly}` and dropping the conditional wrapper so the guard lives in one place, matching the sibling control's pattern.
    • Inline prop defeats memo · Line 640-640
      `currentTheme?.json_data || ''` is re-evaluated inline on every render, so when `json_data` is empty a fresh `''` is produced each time. `ThemeColorPickers` feeds this into `useMemo(() => tryParseThemeJson(jsonData), [jsonData])` (ThemeColorPickers.tsx line 133); string literals compare by value so behavior is correct, but a memoized prop would keep the parse memo stable. Minor; align with the memoized `onJsonDataChange` callback.
  • superset-frontend/plugins/plugin-chart-echarts/src/Bullet/controlPanel.tsx - 3
    • Eager t() in label · Line 70-70
      The repo's `i18n-strings/no-eager-t-in-config` ESLint rule (enabled for `**/controlPanel.*` in `eslint.config.minimal.js`) and the `BaseControlConfig` docs in `superset-ui-chart-controls/src/types.ts` prescribe the lazy form: eager `t()` evaluates at module load, before i18n initializes, so the label can stay in the fallback language. Use `label: () => t('Range colors')`.
    • Eager t() in description · Line 73-75
      Same eager-`t()` issue as the `label` on line 70: `description: t(...)` is evaluated at module load, before i18n initializes, per the `no-eager-t-in-config` rule enabled for `**/controlPanel.*` and the `BaseControlConfig` docs in `superset-ui-chart-controls/src/types.ts`. Wrap it as `description: () => t(...)` so the description re-resolves at render time.
    • Duplicated visibility predicate · Line 76-76
      This `visibility` predicate is byte-identical to the one on the sibling `range_labels` control (line 61), giving the file three copies of the same condition. Extracting a shared predicate beside `config` keeps `range_labels` and `range_colors` in sync if the `ranges` visibility rule ever changes.
  • superset-frontend/plugins/plugin-chart-echarts/src/BigNumber/BigNumberPeriodOverPeriod/utils.ts - 2
    • Duplicated tint opacity constant · Line 181-181
      The ~10% pill tint is encoded twice: `COMPARISON_TINT_ALPHA_HEX` ('1A', line 123) for hex colors and the literal `0.1` here for rgb()/rgba() colors. If the tint is ever tuned, the two paths diverge and pills built from hex vs. rgb theme tokens render different opacities. Consider deriving both from one constant, e.g. `COMPARISON_TINT_ALPHA = 0x1a / 0xff`.
    • Fallback yields invisible pill text · Line 187-191
      If `resolvedColor` is an unrecognized format (named CSS color, 3/4-digit hex), all three tokens become the same value, so the pill renders its text in the same color as its background — invisible text. No current producer emits such values (picker emits 6/8-digit hex; tokens resolve to hex/rgb), so this is future-proofing: consider a theme-neutral background fallback.
  • superset-frontend/src/explore/components/controls/ColorPickerControl.tsx - 1
    • Exported mutable shared constant · Line 30-30
      Exporting `SPECIAL_COLORS` makes it a shared mutable module binding: `as const` enforces readonly only at type level, so an importer could still mutate it at runtime (e.g. via `Object.assign`), corrupting color resolution in `toDisplayHex` and `handleChange`. Wrapping in `Object.freeze` keeps literal types while making the shared map immutable. No importer exists yet, so this is forward-looking.

Dashboard hydration runs this migration before applying the dashboard’s color_scheme override, so a legacy Gauge saved under palette A now keeps A’s literal interval colors on a dashboard using palette B. Could dashboard rendering retain the palette-relative indices rather than freezing them before the effective palette is known?

…color migration

Keep positional scheme colors for bounds without a legacy index, resolve
against the default scheme when the saved scheme is unregistered, and use a
placeholder for the interval label so translators control word order.

The old text input was keyboard-editable, but these rows now use a click-only color-picker trigger with no tab stop or Enter/Space handler, so keyboard-only users cannot change interval colors. Could the picker expose a focusable, keyboard-activatable trigger?

    • Migration bakes fallback scheme colors · Line 46-46
      Non-strict `get(colorScheme)` changes `handleDeprecatedControls` (store.ts:143): for a chart whose `color_scheme` is unregistered, migration now bakes default-scheme hexes into `interval_colors` instead of skipping (strict lookup returned '' and `resolved.some(c => c !== '')` was false). The renderer re-resolves the scheme every render, so a later-registered scheme would self-heal before; the baked snapshot locks wrong colors in. Consider skipping migration when `get(colorScheme, true)` is undefined. ([CWE-471](https://cwe.mitre.org/data/definitions/471.html))

Rebinding a Gauge's dataset through MCP update_chart drops these custom colors: _GAUGE_PRESENTATION_FORM_DATA_KEYS preserves interval_color_indices but not interval_colors, and the replacement params are saved without them. Could the new field be preserved during rebinding, with a regression asserting the picked colors survive?

A saved Gauge now uses interval_colors here, but its MCP Vega-Lite preview still reads only interval_color_indices in _prepare_gauge_preview, so custom red/green bands appear in the default palette instead. Could the preview honor the same explicit-color precedence?

With interval_colors: ['#ff0000'] and legacy indices 3,1, the renderer uses the second palette color for the missing second entry, but this picker displays the first; editing only the first row then persists that different color into the untouched second band. Could populated new arrays use the renderer's positional fallback instead of resurrecting legacy indices?

// A custom `range_colors` entry wins; otherwise fall back to the
// default theme-token ramp exactly as before this control existed, so
// Bullet charts saved without `range_colors` are unaffected.

Choosing a black range fill with Show labels enabled makes its label unreadable in the light theme: the label sits inside the band and still uses the dark colorTextSecondary foreground. Could custom fills get a contrasting label color or place the label outside the fill?
