Pithed Bixa
Pithed Bixa (#860D27) is a deep 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 (347°, 82%, 29%) places it in the highly saturated band at a dark lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. 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.
Etymology
Old English piþa, pith / inner stalk — past-participle of pith. As a color modifier, pithed implies a deep-and-cored-out quality where the visual surface has been excavated to reveal interior darkness. Sits at the deep-and-architectural end of the grid, parallel to hollowed and cored.
Bixa orellana, the proper genus name of the annatto shrub — the South American plant whose seed pulp gives the red food coloring of Latin American cuisine and the body paint of indigenous Amazonian peoples. The color refers to fresh bixa pulp: a saturated, slightly orange red with the matte finish of plant pulp. Warmer than annatto, deeper than tangerine.
