Bright Wakatake

#21e5bd
Notes

Bright Wakatake (#21E5BD) 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 (168°, 79%, 51%) 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

Bright
adjective

Old English beorht, shining, luminous — cognate with the German Bracht, splendor. Applied to color since at least the medieval period for hues that read as luminous: not just light in value but optically active, as if scattering more light back than a dimmer color of the same lightness would. Sits at the bright-bucket center alongside vivid and brilliant.

Wakatake
noun

Japanese for young bamboo — and the soft blue-green of fresh Phyllostachys shoots before they mature to aotake. Wakatake-iro signals seasonal renewal in Japanese textile vocabulary. The color refers to a young bamboo shoot in spring: a soft, slightly cool yellow-green-blue with the satin finish of fresh culm. Lighter than aotake.

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.
