Kukkiri - Color Replacement

Select any two layers to instantly check their color contrast against WCAG 2.1 standards. Kukkiri reads fill colors from your selection, assigns the first as foreground and second as background, and shows you the contrast ratio with pass/fail results for AA, AAA, Normal Text, Large Text, and UI Components.

When colors don't meet your target level, Kukkiri suggests the closest compliant alternatives — adjusted by lightness or subtle hue shifts — so you stay as close to your original palette as possible. Preview each suggestion live on the canvas before committing, and swap between options to find the best fit.
