Create accessible designs in seconds with this minimalist, nononsense color tool.

Stop guessing whether your color combinations meet accessibility standards. This professional utility helps designers and frontend developers generate balanced palettes and verify contrast ratios against both white and black backgrounds according to WCAG 2.1 guidelines (AA/AAA).

Built with a clean blackandwhite interface, the tool eliminates visual noise so you can focus on what really matters: making your content readable for everyone.

How it works:

Pick a base color using the native color picker or type a HEX code (e.g. #3498db).

The tool instantly generates five harmonious variations (complementary, triadic and analogous hues).

For each color you get:

Contrast ratio against white and black
