Gleaming Tit

#21b35c
Notes

Gleaming Tit (#21B35C) is a true green with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (144°, 69%, 42%) 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 magenta. 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.

Tit
noun

The family Paridae — small woodland songbirds — particularly Cyanistes caeruleus (Eurasian blue tit) whose males display turquoise crowns and yellow underparts. The color refers to a male blue tit's crown: a saturated, slightly cool deep blue-green with the satin finish of structural-and-pigment feather color.
