Punchy Coreopsis

#acba2f
Notes

Punchy Coreopsis (#ACBA2F) is a true yellow with a warm character. It leans warm, pulling light toward red, orange, and yellow. Naturally inviting, it suits editorial and hospitality contexts. Its HSL profile (66°, 60%, 46%) 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

Punchy
adjective

A modern adjectival form of punch, to strike sharply. Used as a color word since the early twentieth century for hues that read as highly contrasting and visually loud. Punchy red, punchy yellow: the implication is full saturation combined with optical impact. Sits across the bold and bright buckets, near vivid and striking.

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.
