Color Blueprints — 58 WCAG-verified colour systems

Stop rebuilding accessible palettes from scratch. Color Blueprints contains 58 ready-made colour systems, each with light and dark modes and 35 semantic roles.

Included formats: CSS custom properties, Tailwind v3, Tailwind v4, W3C Design Tokens, Figma Variables JSON, Tokens Studio JSON and Adobe ASE.

The pack includes 4,060 colour values and a 3,364-row contrast report. Body text targets 7:1, accents and status colours target 4.5:1, and borders and focus rings target 3:1 under the documented checks. Primary and secondary colours also retain a separate lightness cue in greyscale.

All colour values were generated by our own system; nothing was copied from a colour atlas, standard or third-party palette. Commercial use, unlimited projects, modification and no attribution are allowed. Redistribution or resale of the files themselves is not allowed.

This pack guarantees only the documented colour-pair checks. It does not by itself make an entire website WCAG-conformant. One-time purchase; no subscription or support contract.
