About the Color Converter & Picker
Pick a colour or type any HEX, RGB or HSL value to see it in every other notation, copy the CSS you need, and generate tints, shades and a matching palette. A contrast checker shows whether text on that colour meets WCAG AA and AAA.
Frequently asked questions
What contrast ratio do I need?
WCAG AA requires 4.5:1 for normal text and 3:1 for large text; AAA requires 7:1 and 4.5:1.
