Adamant Bow Crimson

#b2316a
Notes

Adamant Bow Crimson (#B2316A) is a true magenta with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (333°, 57%, 45%) 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.

Etymology

Adamant
adjective

Greek adámas, unconquerable — derived from a- (not) plus damnan (to subdue). As a color modifier, adamant implies a saturated-and-rock-hard quality where the hue maintains diamond-hard pigmentation. Sits at the bold-and-resilient end of the grid, parallel to indomitable and ironclad in usage.

Bow
modifier

Old Norse bógr, bow / shoulder. As a color modifier, bow implies a ship's-front-prow quality, the visual register of Royal-Navy-and-merchant-marine-bow hand-built ship's-front-prow-and-figurehead bow-and-cutwater maritime-architecture surfaces under ship's-front-bow-and-prow maritime-headway light. Sits at the modifier-and-nautical end of the grid, parallel to prow and hull in usage.

Crimson
noun

From the Old Spanish cremesin, itself from the Arabic qirmiz — the kermes scale insect, dried and ground into a brilliant carmine dye prized in the medieval Mediterranean. For centuries the most expensive red on a draper's shelf, reserved for cardinals, kings, and the cloth that gave English the word crimson. Cooler than scarlet, deeper than rose; the color of pomegranate seeds and a serious occasion.
