Colour relationships

Colour models

HEX and RGB describe red, green and blue light. HSL expresses hue, saturation and lightness; HSV uses value instead of lightness. CMYK approximates cyan, magenta, yellow and black ink, but browser conversions cannot replace a printer colour profile.

Using palettes

Tints mix a colour toward white, shades toward black, complementary colours sit opposite on the hue wheel, and analogous colours sit nearby.

FAQ

Why can converted values differ by one?

Colour models require rounding; a round trip can differ by one channel value without a visible change.
