Armored Alkanet

#a21f11
Notes

Armored Alkanet (#A21F11) 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 (6°, 81%, 35%) places it in the highly saturated band at a mid 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 cyan. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Armored
adjective

Old French armëure, armor — past-participle of armor, derived from Latin arma (weapons). As a color modifier, armored implies a saturated-and-armor-clad-and-defensive quality, the deep-rich color of medieval-knight full-plate-armor visible-and-formidable battle-presence. Sits at the bold-and-fortified end of the grid, parallel to ironclad and shielded.

Alkanet
noun

Anchusa tinctoria, the Mediterranean borage whose roots yield a red dye used since classical times for cosmetics and wine coloring. The color refers to fresh alkanet-dyed wool: a saturated, slightly cool deep red with the matte finish of plant-and-mordant dye. Cooler than madder, deeper than crimson.

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.
