Gleaming Uvarovite

#37b03b
Notes

Gleaming Uvarovite (#37B03B) is a true green with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (122°, 52%, 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 violet. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Gleaming
adjective

The progressive participle of gleam, to shine intermittently. Used as a color word for hues with the slight optical motion of a polished or wet surface. Gleaming gold, gleaming red: the implication is luminance combined with the optical impression of specular highlight. Sits in the bright-and-glossy corner alongside lustrous.

Uvarovite
noun

A chromium-rich green garnet — mined principally in the Russian Urals, Finland, and Quebec. Named for Russian Count Sergei Semenovich Uvarov. The color refers to drusy uvarovite crystals on chromite matrix: a saturated, slightly cool deep emerald-green with the gem's signature internal fire.

Display P3 representation

The CSS Color 4 wide-gamut form of this color. Both swatches render the same color on every display — the P3 form only diverges from sRGB when a designer pushes channels outside sRGB's reach.

This color is chromatic enough that authoring it as P3 native (instead of clamping to sRGB) gives a perceptibly more saturated render on wide-gamut displays — modern Macs, iPhones, iPads, and most recent OLED laptops.
