## I have read the [CONTRIBUTING.md](https://github.com/supabase/supabase/blob/master/CONTRIBUTING.md) file. YES ## What kind of change does this PR introduce? Bug fix ## What is the current behavior? `text-contrast` / `text-foreground-contrast` resolve to `--primary-foreground`, which is always the darker of surface / foreground lightness (text for the green primary fill). In light mode that is near-black, so contrast text on inverted fills is wrong: on true black (`bg-black`) it disappears; on dark fills like `bg-red-900` it shows as a black icon instead of white. Visible regression on the design-system colour usage page: the `text-contrast` swatch only shows "Postgres" on hover. Regression from the colour system rewrite (#47288), which aliased `--foreground-contrast` → `--primary-foreground`. ## What is the new behavior? `--foreground-contrast` is defined again as a surface-based inverse of `--foreground` (light in light mode, dark in dark mode). Tailwind utilities `text-contrast` and `text-foreground-contrast` map to it. `--primary-foreground` is unchanged and still used for text on the primary fill. ## Additional context ### Callsites to test (light mode especially) | Where to look | What to check | |---|---| | [Design system → Colour usage](https://design-system-git-fix-text-contrast-token-supabase.vercel.app/design-system/docs/color-usage) | Under **Text**, the `text-contrast` swatch shows "Postgres" without hovering | | [Studio staging → Auth Users](https://studio-staging-git-fix-text-contrast-token-supabase.vercel.app/project/_/auth/users) → open any user | Boolean fields (e.g. confirmed): check/X on the black circle should be **white** (not missing) | | [Studio staging → Support new](https://studio-staging-git-fix-text-contrast-token-supabase.vercel.app/support/new) → upload a file | Red remove (`X`) badge should be a **white** X (prod currently shows black) | | [www → Contribute](https://zone-www-dot-com-git-fix-text-contrast-token-supabase.vercel.app/contribute) → apply at least one filter | Filter count badge: **white** number on black | | [Studio staging → Support link](https://studio-staging-git-fix-text-contrast-token-supabase.vercel.app/support/link) success state (after linking a ticket) | Check on the brand badge should use contrast text (light on brand in light mode) | `Announcement` (`text-foreground-contrast` dismiss icon) is not currently mounted in any app — covered by the design-system / token check above.
packages/ui
Supabase's shared React component library. Built on Radix UI primitives and shadcn/ui, styled with Tailwind CSS, and used across all Supabase apps.
Usage
Import from the 'ui' package alias:
import { Badge, Button, Input } from 'ui'
Some of the components have the _Shadcn_ suffix. These components should be preferred, they're in a process of replacing the other ones.
Utilities
// deep object merge (used for themes)
import { clipboard, cn, mergeDeep } from 'ui' // clsx + tailwind-merge
// copy-to-clipboard helper
Styling conventions
- Tailwind only — no inline styles or CSS modules.
- Use shadcn semantic pairs (
bg-card text-card-foreground,bg-muted text-muted-foreground,bg-tertiary text-tertiary-foreground) rather than hardcoded colors. Legacy utilities such astext-foreground-lightandborder-defaultare compatibility aliases only. - Themes set the core
--hue(or the split--surface-hue/--primary-hue),--chroma,--surface,--foreground-lightness, and--contrastinputs, plus their--muted-foreground-leveland--tertiary-foreground-levelhierarchy. Semantic colors are derived from them in OKLCH;--contrast: 1is the baseline and the supported adjustment range is0.75to1.25. - The workspace root owns the actual
tailwind.config.js. The file in this package is a stub for IntelliSense only.
