Overview
Build a colour palette from one hex colour: complementary, analogous, triadic, split-complementary and tetradic harmonies (hue rotations at the same saturation and lightness), plus six shades from light to dark, all as hex codes, with the base colour's HSL. Use for UI themes, charts, brand kits or slide decks; to check text readability on a colour use color_contrast.
