Buzzed Coreopsis

#b5c53b
Notes

Buzzed Coreopsis (#B5C53B) is a true yellow with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (67°, 54%, 50%) 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

Buzzed
adjective

Imitative-onomatopoeic origin — past-participle of buzz, evoking the sound of bee-hum. As a color modifier, buzzed implies a saturated-and-vibrating-and-active quality, the bright color of insect-pollinator and neon-lamp low-amplitude-buzz visual-vibration. Sits at the bright-and-active end of the grid, parallel to jazzed and wired in usage.

Coreopsis
noun

The genus Coreopsis — North American composite-family annuals (also called tickseed) whose bright yellow ray flowers fill prairie restorations and pollinator gardens. The color refers to a C. tinctoria bloom: a saturated, slightly red yellow with the matte finish of multi-rayed composite flower.
