Vitreous Catmint

#0a6439
Notes

Vitreous Catmint (#0A6439) is a deep teal 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 (151°, 82%, 22%) places it in the highly saturated band at a dark 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 magenta. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Vitreous
adjective

Latin vitreus, glass-like — derived from vitrum (glass). As a color modifier, vitreous implies a clear-and-glassy quality where the hue carries the optical clarity of polished crown-glass. Sits at the crisp-and-clear end of the grid, parallel to pellucid and crystalline in usage.

Catmint
noun

The genus Nepeta — particularly N. mussinii (catmint), the cottage-garden perennial with silver-green foliage and lavender-blue flower spikes. The color refers to a fresh catmint clump in May: a soft, slightly cool gray-green with the matte finish of small mint-family leaves. Cooler than santolina.

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.
