Color Converter
Convert HEX, RGB, HSL, HWB and CMYK colours.
Contrast ratio (WCAG 2)
WCAG AA needs 4.5:1 for normal text and 3:1 for large text (24 px, or 18.66 px bold). AAA needs 7:1 and 4.5:1. CMYK values here are a simple formula without a printer profile, so printed colours can differ.

Questions people ask
How do I convert HEX to RGB?
Split the six digits into three pairs and read each pair as a hex number. #3B82F6 is rgb(59, 130, 246).
What contrast ratio do I need?
WCAG AA needs at least 4.5:1 for normal text and 3:1 for large text. AAA needs 7:1 for normal text.

No. It uses the standard formula with no colour profile. Printers use profiles such as FOGRA or GRACoL, so ask your print shop for exact values.
