HEX vs RGB vs HSL: Which Color Format Should You Use?

Compare the most common CSS color formats for hand-editing, readability, and accessibility workflows.

Editing

HSL makes it easy to lighten, darken, or desaturate a color. HEX and RGB require mental math.

Compatibility

All three are fully supported in CSS and every modern browser. HEX is the most common in design tools.

Best For
