@polyxd/ds-antd

The Ant Design design-system pack for Polyxd. It has DTCG 2025.10 token files that satisfy the Polyxd semantic token contract (packages/spec/tokens/semantic-contract.json, v0.1.0) in light and dark modes.

npm run check -w @polyxd/ds-antd     # contract check, both modes
npm run generate -w @polyxd/ds-antd  # regenerate tokens/*.json

Tiers

Ant's own token names are kept as they are, so you can trace every semantic token back to theme.useToken() / ConfigProvider names.

Tier	File	Contents
Reference (primitive)	tokens/primitive.json	antd.seed.* (the default seed: colorPrimary, fontSize, borderRadius, controlHeight, motionUnit, preset seed colours, …). antd.palette.<preset>.1..10 (presetPalettes, e.g. antd.palette.blue.6) and antd.paletteDark.<preset>.1..10 (presetDarkPalettes). antd.palette.{primary,success,warning,error,info}.1..10 and the paletteDark equivalents: the palettes each algorithm derives from the colour seeds.
System	tokens/system.json	antd.token.* map/alias tokens with the same value in both algorithms: fontSize*, lineHeight*, fontFamily, borderRadius*, controlHeight*, padding*, margin*, size*, lineWidth*, motionDuration*, motionEase*, screen*, zIndex*, … Tokens the seed passes through unchanged alias antd.seed.*. Polyxd additions: polyxd.sys.{font,radius,motion,focus,state.disabled}.
System, per mode	tokens/system.light.json, tokens/system.dark.json	antd.token.* colour and boxShadow* tokens from defaultAlgorithm / darkAlgorithm. A colour is an alias to a palette step wherever the algorithm took it from one (for example, colorPrimary → {antd.palette.primary.6}, colorPrimaryActive → .7). Polyxd additions: polyxd.sys.color.solid.* (opaque composites, see below), polyxd.sys.color.<role> (roles that differ by mode or were adjusted for contrast, chart colours) and polyxd.sys.state.{hover,pressed,focus}.
Semantic	tokens/semantic.json	The Polyxd contract tokens, each an {alias} to an antd.token.*, or to a polyxd.sys.* token where Ant has no directly usable value. The file is the same in both modes.

manifest.json merges the files for each mode in this order: primitive → system → system. → semantic.

The main semantic mappings are:

• Surfaces: default and raised are colorBgContainer, because antd cards sit on the container colour and are set apart by a border rather than a tone. Subtle is colorFillAlter (table and collapse headers). Overlay is colorBgElevated (Modal, Popover, Dropdown). Inverse is colorBgSpotlight (Tooltip). Scrim is colorBgMask, used with its alpha.
• Text: default is colorText, muted is colorTextSecondary, inverse is colorTextLightSolid and link is colorLink (adjusted, see Contrast).
• Borders: default is colorBorderSecondary. Strong would be colorBorder, but that was adjusted. Focus is colorPrimaryBorder, the genFocusOutline colour (also adjusted).
• Actions: primary is colorPrimary with colorTextLightSolid text. Secondary is antd's default Button: colorBgContainer, colorText text and a colorBorder outline. Danger is colorError with colorTextLightSolid text. Selection is controlItemBgActive with colorText text.
• Status: background is color<Status>Bg, foreground is color<Status>Text and emphasis is color<Status>. danger uses antd's colorError*.
• Data: positive is colorSuccess, negative is colorError and neutral is colorTextTertiary (antd's icon grey, colorIcon).
• Type: fontFamily is fontFamily everywhere, and letter-spacing is 0. The page title is Title level 2 (fontSizeHeading2 30px), the section title is level 4 (20px) and the item title is level 5 (16px); all three use fontWeightStrong 600. Body default is fontSizeLG (16px) and body small is fontSize (14px). Label default is fontSize (14px) and label small is fontSizeSM (12px). Numeric display is fontSizeHeading3 (24px), the Statistic value size. Every style uses its matching antd lineHeight* token.
• Space: the antd size ladder. Inset is paddingSM/padding/paddingLG (12/16/24). Stack is marginXXS/marginXS/margin/marginXL (4/8/16/32). Inline is marginXXS/marginXS/margin (4/8/16).
• Size, radius and border: target size is controlHeight (32). Icons are fontSizeIcon (12) and fontSize (14), because antd icons inherit the text size. Radius is borderRadiusSM/borderRadius/borderRadiusLG (4/6/8), and full is polyxd.sys.radius.full (9999px). Border widths are lineWidth/lineWidthBold (1/2). The focus ring is lineWidthFocus (3px) with a 1px offset.
• Shadows: raised is boxShadowTertiary and overlay is boxShadowSecondary. boxShadowSecondary is what antd's popovers and dropdowns use, and it is identical to boxShadow, which Modal uses. Every boxShadow* token is parsed into DTCG shadow layers; inset layers get inset: true.
• Motion: instant, short and medium are motionDurationFast/Mid/Slow (100/200/300ms). Long is polyxd.sys.motion.duration-long (400ms). Easing is motionEaseInOut for standard, and the zoom pair antd uses for Modal and Popover for enter and exit: motionEaseOutCirc and motionEaseInOutCirc.

Judgement calls

• Body text is 16px, not antd's 14px. antd's base fontSize is 14px. The contract requires type.body.default ≥ 16px, so body default maps to fontSizeLG (16px, lineHeightLG 1.5). antd's 14px base is still available as type.body.small and type.label.default, so controls keep antd's density.
• Target size is antd's controlHeight (32px). This passes the contract (WCAG 2.5.8, ≥ 24px), but antd's default density is below the 44–48px touch-target guidance of iOS and Material. Use controlHeightLG (40px) or larger for touch-first surfaces.
• Radius keeps antd's small scale: 4/6/8. antd has no pill token.
• Translucent colours. antd's neutrals are alpha colours: colorText is rgba(0,0,0,0.88) in light mode and rgba(255,255,255,0.85) in dark mode. The same goes for colorTextSecondary, colorFillAlter and the light colorBgSpotlight. Semantic colours must be opaque for contrast checks and for renderers that do not composite, so these roles alias polyxd.sys.color.solid.<antdName>: the antd colour composited on that mode's colorBgContainer. The generator checks contrast with the real alpha composited on each actual background. Composited on white, antd's text alphas give its familiar greys: 0.88 → #1f1f1f, 0.65 → #595959, 0.45 → #8c8c8c.
• State opacities: antd shifts colours rather than using state layers. Hover and pressed are the alpha of colorBgTextHover/colorBgTextActive (0.06/0.15 in light, 0.12/0.18 in dark), and focus is the alpha of controlOutline (0.1 in light, 0.31 in dark). These are per mode.
• Chart colours: antd ships no chart palette (that is AntV). Series 1–6 are presets blue, orange, cyan, magenta, green and purple, with the order alternating warm and cool. They use step 6 (the preset's base colour) from presetPalettes in light mode and presetDarkPalettes in dark mode. Where step 6 fails 3:1 against the surface, the series moves to the nearest passing step (see Contrast).
• Long duration: antd defines durations as motionBase + motionUnit × n, with fast ×1, mid ×2 and slow ×3. duration-long extends that ladder by one step (×4 = 400ms).
• Dark shadows: in antd 6.6.4, darkAlgorithm derives shadows from colorShadow rgba(255,255,255,0.2), so the dark boxShadow* layers are white at 1–2.4% alpha. They are vendored as antd computes them.

Contrast

antd's default palette misses several WCAG thresholds. For each contract pair that failed with the natural mapping, the generator moved the role to the nearest step of the same antd palette that passes every pair the role is in. For border.strong it used antd's neutral ladder (colorBorderSecondary → colorBorder → colorTextQuaternary → colorTextTertiary → colorTextSecondary → colorText) instead. npm run generate prints this list. Ratios are WCAG 2.x, with translucent colours composited.

Findings worth knowing:

• antd's primary button (white on #1677ff, 4.10:1) and its light link colour fail WCAG AA 1.4.3 for normal-size text.
• Warning text on the warning background is 1.83:1.
• The default input border #d9d9d9 is 1.41:1, well below the 3:1 non-text minimum.
• The dark primary button (white on #1668dc) passes at 5.19:1, so it was not adjusted.
• The tightest pair after adjustment is dark action.danger.background against the surface, at exactly 3.00:1. Step 5 is the only error step that passes both the white-text pair (≥ 4.5) and the surface pair (≥ 3).
• opacity.state.disabled is adjusted too. antd's disabled content is colorTextDisabled (alpha 0.25), below the contract's 0.3 minimum, so the pack uses 0.45, the next step of antd's text-alpha ladder (colorTextTertiary).
• action.secondary.border stays antd's colorBorder, because the contract has no contrast pair for it. The button label identifies the control.

Regenerating

scripts/generate.ts writes all five token files and gives the same output on every run. It works offline from scripts/sources/antd/antd-tokens.json. Do not edit the token files by hand. The generator also checks every contract contrast pair with alpha compositing, and it fails if a role cannot be brought into compliance.

To refresh the vendored data for a new antd version, use a scratch directory outside the repo. The pack has no npm dependencies on purpose.

cd "$(mktemp -d)" && npm init -y && npm install antd@<version> react react-dom
cp <repo>/packages/ds-antd/scripts/sources/antd/dump-antd-tokens.mjs .
node dump-antd-tokens.mjs > <repo>/packages/ds-antd/scripts/sources/antd/antd-tokens.json

Then update ANTD_VERSION / COLORS_VERSION in generate.ts, manifest.json and this README, and run npm run generate.

The dump holds theme.defaultSeed, the output of theme.defaultAlgorithm(seed) and theme.darkAlgorithm(seed) (map tokens), and theme.getDesignToken({ algorithm }) (map + alias tokens). It also holds presetPalettes, presetDarkPalettes, and generate(seed) / generate(seed, { theme: 'dark' }) for each colour seed.
