Color Converter

Convert any colour between HEX, RGB, HSL, HSV and CMYK, or pick one visually. It checks WCAG text contrast against white and black, finds the nearest CSS colour name, and builds tints, shades and colour harmonies.

Colour formats

HEX (#1A5BC4): red, green and blue as two hex digits each. It is the standard on the web.
RGB (26, 91, 196): the same three values from 0 to 255.
HSL (217°, 77%, 44%): hue, saturation and lightness. It is the easiest format for making lighter or darker versions of a colour.
CMYK: cyan, magenta, yellow and black ink percentages used in printing. This conversion is a simple approximation; printers use colour profiles for exact results.

Contrast (WCAG)

For readable text, WCAG 2.2 asks for a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text (AA), or 7:1 for AAA.

Frequently asked questions

How do I convert HEX to RGB?

Split the six digits into three pairs and convert each from hexadecimal: #1A5BC4 gives 1A = 26, 5B = 91, C4 = 196, so rgb(26, 91, 196).
