Madder Lake
Madder Lake (#A32638) is a true red with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (351°, 62%, 39%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. For a confident two-color system, pair it with its complementary teal. For something softer, pull in its analogous neighbors on either side of the wheel. Red pigment precipitated from the roots of Rubia tinctorum. Dyed the sashes of Napoleonic infantry, the petticoats of Vermeer's women, and the Turkey-red cotton that flooded Europe in the 18th century.
