Accessible Color Palette Generator

Accessible Color Palette Generator is a focused utility that helps you build enterprise UI color systems with accessibility baked in. It generates matched light and dark palettes and applies rules so colors keep similar perceived lightness across UI roles. That approach reduces the guesswork when you need consistent contrast for text, UI elements, and semantic surfaces across themes.

The tool is pragmatic, not flashy. You drop in base hues, tweak tones, and it outputs ramped colors for content, non content, accents and surfaces designed for real interfaces. The generator follows the rules Francis Wu documented in his writeups so the outputs are grounded in a repeatable method rather than random swatches. There is a public GitHub repo and a Medium retrospective that explain the math and tradeoffs if you want to dig in.

It’s a useful, developer-friendly shortcut when building accessible palettes, sometimes needs manual tuning for brand voice. Use it when you need an accessibility-aware starting point for enterprise UI work, then refine tone and nuance by hand. It is a solid generator for teams who want practical accessibility checks, matched light and dark systems, and a method they can reproduce across products.
