Commanding Linarite

#2156af
Notes

Commanding Linarite (#2156AF) is a true azure with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (218°, 68%, 41%) 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 amber. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Commanding
adjective

Latin commendāre, to entrust / order — present-participle of command. As a color modifier, commanding implies a saturated-and-authoritative quality where the hue claims visual leadership of its surrounding palette. Sits at the bold-and-authoritative end of the grid, parallel to authoritative and imperial in usage.

Linarite
noun

A rare lead-copper sulfate mineral — saturated deep blue, mined principally in Linares, Spain (the source of its name). Highly fragile and rarely cut as a gem; valued by mineral collectors for its intense color. The color refers to a fresh linarite specimen: a saturated, slightly cool deep blue with the satin luster of crystallized secondary mineral.

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.
