Saturated Alizarin

#861b6d
Notes

Saturated Alizarin (#861B6D) is a deep magenta 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 (314°, 66%, 32%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. For a confident two-color system, pair it with its complementary green. For something softer, pull in its analogous neighbors on either side of the wheel.

Alizarin
noun

1,2-dihydroxyanthraquinone — the principal anthraquinone dye component of madder root (Rubia tinctorum), first isolated and synthesized in 1869 by Carl Graebe and Carl Liebermann. Alizarin color refers to a freshly alizarin-mordant-dyed wool: a saturated, slightly cool deep magenta with the matte finish of anthraquinone-dye-on-mordanted woolen fiber. The first natural pigment to be replaced by a synthetic.
