Radiant Atriplex

#21c181
Notes

Radiant Atriplex (#21C181) 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 (156°, 71%, 44%) 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

Radiant
adjective

From the Latin radiare, to emit rays — used as a color word since the seventeenth century for hues that read as luminous and emitting. Radiant gold, radiant pink: the implication is high luminance combined with the optical impression of an outward light. Sits in the bright-bucket center alongside glowing.

Atriplex
noun

The genus Atriplex — saltbushes, the salt-tolerant gray-green shrubs of saline desert, beach, and salina habitats from California to Australia. The color refers to a clump of A. canescens in Mojave Desert: a soft, slightly cool silver-green with the matte finish of salt-encrusted leaf.
