YES, IT'S VERMARCABLE
Creative Assets: WCAG Contrast & Design Token Benchmarks
Free, platform-curated reference of stable design-system benchmarks — WCAG contrast minimums, the 8-point spacing grid, sRGB white point and typographic scale ratios — drawn from public W3C, IEC and ICC standards. Helps designers, accessibility auditors and design-token engineers ship compliant color and type systems using authoritative, public-domain figures.
