What it does for you

Readable colors for everyone, without losing your hue

Light grey text on white looks elegant but is hard for many people to read. This Skill computes the contrast of every color pair with the official WCAG 2.2 formulas and, for each failure, suggests two fixes that keep the same hue.

  • Check your whole palette against AA thresholds
  • Get two ready-made fixes for each failure
  • Decide on exact math, never on rounded values
