Neon Tit

#21e8cd
Notes

Neon Tit (#21E8CD) is a true teal with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (172°, 81%, 52%) 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 red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Neon
adjective

Greek néon, new — element-name (atomic-number 10), discovered by William Ramsay in 1898. As a color modifier, neon implies a saturated-and-electric-glow quality, the bright color of Las-Vegas-and-Times-Square neon-marquee gas-discharge-tube emission. Sits at the bright-and-electric end of the grid, parallel to electric and fluorescent in usage.

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.
