Color Format Reference

HEX & RGB

HEX ( #RRGGBB ) is the most widely used format in web design. RGB ( rgb(R, G, B) ) expresses each channel as a 0–255 integer. Both describe colour in the sRGB colour space used by screens.

HSL & HSV

HSL (Hue, Saturation, Lightness) and HSV (Hue, Saturation, Value) are human-intuitive models. Rotating the hue generates harmonious palettes. HSL is natively supported in CSS via hsl() and oklch() .

CMYK & WCAG

CMYK is the subtractive model used in print (Cyan, Magenta, Yellow, Key/Black). WCAG contrast ratios (AA ≥ 4.5:1, AAA ≥ 7:1) ensure text is readable for users with low vision or colour blindness.
