In @.changeset/mosaic-gray-scale.md:
- Around line 1-2: Update the changeset frontmatter to declare a semver release
for the `@clerk/ui` package, and add a concise summary describing the change so
Changesets versions and publishes the package.
In `@packages/swingset/src/stories/banner.mdx`:
- Line 62: Update the neutral color guidance in the banner documentation to
describe its fill as the 4% neutralAlpha wash derived from --cl-color-neutral,
replacing the incorrect --cl-color-foreground mix description; keep the existing
border-token guidance unchanged.
In `@packages/ui/src/mosaic/components/button/button.styles.ts`:
- Around line 16-19: Shorten the multi-line token-mapping comment in
packages/ui/src/mosaic/components/button/button.styles.ts lines 16-19 to one
terse rationale, or remove it if the token names are self-explanatory; likewise
shorten or remove the badge color explanation in
packages/ui/src/mosaic/components/badge/badge.styles.ts line 13. Preserve the
styling implementation unchanged.
In `@packages/ui/src/mosaic/tokens.stylex.ts`:
- Line 57: Update the token definition near --cl-color-brand to preserve
--cl-color-primary as a deprecated compatibility alias, ensuring existing
overrides continue to affect components that consume the brand token. Retain
equivalent aliases for the other removed public primary tokens, following the
existing token alias conventions.
- Line 68: Update the positive and warning foreground token values in the stylex
token definitions to use a dark color that achieves at least 4.5:1 contrast
against their corresponding fills in both light and dark schemes, replacing the
current white foregrounds while preserving the existing token names and scheme
structure.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Document the neutral wash with the correct token source.
The new neutralAlpha scale is derived from --cl-color-neutral, which uses black in light mode and white in dark mode. This paragraph instead describes the neutral fill as a mix of --cl-color-foreground. Consumers following this guidance can produce a different wash and contrast result.
Describe the fill as the 4% neutralAlpha wash derived from --cl-color-neutral.

@maxyinger, the implementation does not mix --cl-color-foreground.
packages/ui/src/mosaic/components/banner/banner.styles.ts Line 48 uses neutralAlpha['4'].
packages/ui/src/mosaic/tokens.stylex.ts Line 90 defines it as:
color-mix(in oklab, var(--cl-color-neutral) 4%, transparent)The transparent result composites over the banner’s existing background. It is therefore a 4% neutral wash, not a 4% foreground wash. The documentation should reference neutralAlpha and --cl-color-neutral, as the original finding states.

Description
Aligns the Mosaic color tokens with the Figma design system. The semantic tokens are restructured into Figma's foreground, background, border, brand, and status groups, and every achromatic token is derived from two public roots instead of a gray scale.
--cl-color-neutral(black on light, white on dark) is mixed into--cl-color-background(white on light, gray 900 on dark) at a fixed percentage per color scheme. Grays have zero chroma, so an oklab mix is linear in lightness and the percentages reproduce the Figma steps exactly. Overriding--cl-color-neutralalone retints the whole ramp.--cl-color-background-subtle--cl-color-border-subtle--cl-color-border--cl-color-input--cl-color-foreground-disabled--cl-color-input-placeholder--cl-color-foreground-secondary--cl-color-foreground--cl-color-ringAdds public
--cl-color-<name>-alpha-100|200|300tokens for neutral, negative, positive, and warning: 6, 8, and 12 percent of the matching solid color overtransparent. Every hover, pressed, resting, and focus wash in button, badge, menu, item, avatar, banner, input, and OTP reads from those tokens instead of an inlinecolor-mix, so they composite the same on any backdrop and retint when the solid color is overridden. Icon frame's filled treatment reads--cl-color-background-subtle.Adds
--cl-shadow-sm|md|lg, matching the Figma effect styles. Every layer is a wash of--cl-color-neutral, so shadows are #000 on light rather than the foreground. In dark the drop layers fall away and only the hairline ring stays. Card, dialog, and profile takelg; menu, select, combobox, and phone input popups takemd; the drawer sheet takessm.Brand and the status colors stay literal. The dialog and drawer scrims stay a literal black wash by design, since they composite over the host page. The input hover border and focus shadow still use literal grays.
