Sunlit Lemonade

#c9d536
Notes

Sunlit Lemonade (#C9D536) is a true yellow with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (65°, 65%, 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 blue. 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.

Lemonade
noun

The classic citrus drink — fresh lemon juice diluted with water and sweetener, served chilled in summer. Lemonade refers to the color of fresh-squeezed lemonade in a clear glass: a soft, slightly cool pale yellow with the optical clarity of citrus-juice-and-water. Cooler than mayonnaise.

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.
