Sharp Linarite

#2b9ce9
Notes

Sharp Linarite (#2B9CE9) 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 (204°, 81%, 54%) 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 orange. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Sharp
adjective

Old English scearp, cutting, pointed — applied metaphorically to color since the seventeenth century for hues that read as definite and edge-defined. Sharp red, sharp green: the implication is saturation combined with high-contrast crispness. Sits in the bright-bucket center alongside crisp and clear, with a slightly more incisive edge.

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.
