Sharp Daffodil

#adb221
Notes

Sharp Daffodil (#ADB221) 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 (62°, 69%, 41%) 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

Sharp
adjective

Old English scearp, cutting, pointed — applied metaphorically to color since the seventeenth century for hues that read as definite and edge-defined. Sharp red, sharp green: the implication is saturation combined with high-contrast crispness. Sits in the bright-bucket center alongside crisp and clear, with a slightly more incisive edge.

Daffodil
noun

Narcissus pseudonarcissus, the wild daffodil of British and European woodland. The color is the trumpet-shaped corona of a fully open daffodil at peak spring: a saturated, slightly orange-shifted yellow with the satiny finish of waxy petal tissue. Warmer than lemon, brighter than buttercup, with the seasonal weight of a flower that arrives before the trees have leaves.
