About Accessible Palette
Accessible Palette uses the CIELAB and LCh color models to generate color scales where each step has the same perceived lightness across different hues. You set starting colors by lightness, chroma and hue, and the tool produces steps from 50 to 900.
Every step shows its WCAG 2 contrast ratio and a WCAG 3 score, so a whole family of colors can share predictable accessibility. It suits designers who need several brand and status colors that behave consistently in an interface.
Strengths
- Consistent perceived lightness across hues
- Shows WCAG 2 and WCAG 3 contrast for each step

Limitations
- Assumes familiarity with LCh values
