fix(CustomTooltip): theme tooltip content against its own surface by yi-nuo426 · Pull Request #1884 · layer5io/sistent

yi-nuo426 · 2026-10-23T23:30:08Z

Symptom: tooltip content using mode-dependent tokens (e.g. Divider) was invisible on light pages because the chip is always dark.
Root cause: surface painted from bgColor literal, content themed from the ambient palette.
Fix: CustomTooltip wraps its title in a ThemeProvider whose mode follows bgColor's contrast (only when it differs from the page mode, preserving branded themes); tooltip text color follows the same mode. Removed the CollaboratorAvatarGroup workaround. Added tests.

Summary by CodeRabbit

Bug Fixes
- Tooltip text now uses colors suited to its background, improving readability on both light and dark surfaces.
- Collaborator controls now follow the standard theme styling for dividers, borders, and text.

…own surface The tooltip paints bgColor (default #141414) in both palette modes, but its content styled from the ambient theme, so mode-dependent tokens such as palette.divider were wrong on light pages. Wrap the title in a ThemeProvider whose mode follows the contrast of bgColor, only when it differs from the page mode so branded themes are preserved. Remove the CollaboratorAvatarGroup call-site workaround. Fixes #1783 Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com> Signed-off-by: Lee Calcote <lee.calcote@layer5.io>

📝 Walkthrough

CustomTooltip now selects a palette mode based on its background and provides a matching theme to tooltip content when needed. Tests cover dark and light surfaces. CollaboratorAvatarGroup removes explicit divider and button colors.

Changes: CustomTooltip surface theming

Layer / File(s)	Summary
Derive and provide the surface theme `src/custom/CustomTooltip/customTooltip.tsx`, `src/__testing__/CustomTooltip.test.tsx`	CustomTooltip determines a palette mode from the background contrast. It uses the matching text color and provides a custom theme when the ambient mode differs. Tests cover the default dark surface, a dark page, and a white background.
Remove collaborator tooltip color overrides `src/custom/CollaboratorAvatarGroup/CollaboratorAvatarGroup.tsx`	The divider and button no longer set explicit colors. The unused `alpha` import and the tooltip workaround comment are removed.

Full details: Linked Issues check

Explanation

The PR satisfies the coding requirements in [#1783]. CustomTooltip infers a light or dark surface mode from bgColor, provides a matching ThemeProvider to title content when the modes differ, and sets tooltip text color for that surface. This aligns mode-dependent tokens such as palette.divider with the surface. The CollaboratorAvatarGroup call-site workaround is removed. Tests cover default dark content on a light page, matching dark mode, and a light bgColor.

Full details: Out of Scope Changes check

Explanation

The changes stay within [#1783]. The CustomTooltip implementation and tests address the surface-theme mismatch. The CollaboratorAvatarGroup style removal is the required removal of the interim workaround. No global palette change or unrelated component behavior is introduced.

Resolve valid light CSS backgrounds before selecting dark mode.

If bgColor is white or a CSS variable that resolves to white, MUI rejects the value in getContrastRatio(). This fallback then selects dark mode while the tooltip paints a white background. The resulting white text is unreadable. Resolve the painted color before calculating contrast, or require an explicit mode when the color cannot be resolved. (raw.githubusercontent.com)
