Certain Kunzite

#841b6d
Notes

Certain Kunzite (#841B6D) 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 (313°, 66%, 31%) 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.

Etymology

Certain
adjective

Latin certus, fixed / sure — sharing root with English concern and certify. As a color modifier, certain implies a saturated-and-unambiguous quality where the hue declares its character without hesitation. Sits at the bold-and-confident end of the grid, parallel to assured and decisive in usage.

Kunzite
noun

Pink variety of the lithium-aluminum silicate spodumene — first described from the San Diego gem-deposits of California in 1902 by George Frederick Kunz. The pink color comes from manganese substitution. Kunzite color refers to a faceted San-Diego-area kunzite: a saturated, slightly cool deep magenta with the glassy finish of manganese-substituted spodumene gem crystal. Pleochroic between deep-pink and pale-violet.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
