Understanding Color Models and Conversions

This all-in-one converter takes a single HEX color and instantly expresses it in every model you need for web and print: normalized HEX, RGB, HSL, HSB/HSV, and CMYK. Translating between these spaces is essential for matching brand guidelines, writing CSS, and preparing artwork for print.

HEX & RGB

HEX is a base-16 form of RGB. Both describe an additive mix of red, green, and blue light (0–255 per channel) — the native model for screens and CSS.

HSL & HSB

Both use Hue (0–360°) but differ on the rest: HSL pairs Saturation with Lightness, while HSB (a.k.a. HSV) pairs Saturation with Brightness — the model most color pickers use.

CMYK

Cyan, Magenta, Yellow, and Key (black) is the subtractive model used by printers. The values here are a device-independent approximation — exact output depends on your paper and ICC profile.

100% client-side

Every formula runs in your browser — no color data is ever uploaded. Need a single direction instead? Try the dedicated HEX → RGB, RGB → HSL, or HEX → CMYK tools.
