TypeScript definitions for apca-w3

APCA: the Accessible Perceptual Contrast Algorithm, a modern contrast method that improves readability contrast on self-illuminated displays. Developed for the W3C's WCAG 3 and other standards.

Axe rules to check against APCA bronze and silver+ conformance levels.

Sass implementation of the [Accessible Perceptual Contrast Algorithm (APCA)](https://git.apcacontrast.com/) for the WCAG 3.0 specification.

JS color calculator for composing colors with consistent APCA contrast ratio

Storybook Accessibility addon with APCA (WCAG 3) support

APCA (Accessible Perceptual Contrast Algorithm) contrast calculation for @pawells/colors — opt-in W3-licensed accessibility contrast utility, kept separate so the MIT-licensed core package carries no field-of-use restrictions.

Storybook a11y reporter with APCA support for CI/CLI

Reactive OKLCH color-system designer — thin composer over the @zakkster color stack. Curve-driven scale generation, APCA contrast, design-token exports, and Canvas slider-track baking.

Fail your build when your color palette isn't accessible. WCAG 2.2 + APCA + color-blindness grading for your design tokens.

Check color contrast compatibility (WCAG 2.1 + APCA), suggest fixes, and validate design-token palettes.

A Bridge for WCAG_2 contrast using APCA (Advanced Perceptual Contrast Algorithm), technology.

WCAG & APCA contrast ratios for hex and OKLCH colors, plus readableOn, isReadable and score helpers. Part of huekit, the OKLCH toolkit for designers.

One color → 150+ design tokens. OKLCH-based theme generator with CSS variables, Tailwind config, DTCG export, APCA contrast, tonal palettes, and color blindness simulation. Zero deps, strict TypeScript.

A generated colour system: CSS custom properties, a Tailwind v4 theme, DTCG 2025.10 tokens and SCSS. Solved in OKLCH against APCA contrast targets, not hand-picked.

Anti-slop UI/UX design discipline for your Pi agent — anchors a lintable DESIGN.md, runs deterministic slop-audit gates (APCA contrast + tokens + states + slop tells), works with text-only models, ships reference design-system presets.

Readable text on any background—WCAG & APCA aware React components and color helpers (TypeScript).

Data-viz palette designer. Perceptually linear, CVD-safe, APCA-annotated sequential, diverging and categorical ramps.

CLI for APCA (Lc) accessibility contrast checking — the algorithm WCAG 3 is built around.

UI/UX design audit tool for Claude Code. Scores projects across 12 dimensions: color contrast, typography, accessibility, layout, and more. WCAG 2.2, APCA, and OKLCH color science. Zero dependencies.
