Sunlit Seagrass
Sunlit Seagrass (#47C271) is a true green with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (140°, 50%, 52%) 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
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.
Marine flowering plants — distinct from algae — that form underwater meadows in shallow coastal waters worldwide. Genera include Zostera, Posidonia, Thalassia. The color refers to a tropical seagrass meadow at low tide: a soft, slightly cool deep blue-green with the satin finish of submerged grass-leaves.
