Sunlit Gyokuro

#21be57
Notes

Sunlit Gyokuro (#21BE57) 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 (141°, 70%, 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

Sunlit
adjective

Old English sunne (sun) plus past-participle līehted. As a color modifier, sunlit implies a saturated-and-direct-sunlight-illuminated quality, the bright color of southern-Mediterranean and Greek-island afternoon-sun direct-illumination surface emission. Sits at the bright-and-warm end of the grid, parallel to radiant and brilliant in usage.

Gyokuro
noun

The premium Japanese green tea grown in shade for three weeks before harvest — concentrating chlorophyll and theanine. Gyokuro (玉露 — jewel dew) is the most expensive non-matcha Japanese tea. The color refers to fresh-brewed gyokuro: a saturated, slightly cool deep blue-green with the optical depth of shaded-leaf tea.

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.
