Warm Cowslip

#bfdb81
Notes

Warm Cowslip (#BFDB81) is a true lime 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 (79°, 56%, 68%) 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 indigo. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Warm
adjective

Old English wearm, of moderate heat — used as a color modifier since the medieval period for hues that read as containing red, orange, or yellow undertones. Warm gray, warm white: not necessarily a temperature, but the optical impression of a slight red-orange shift. Sits across the crisp and neutral buckets.

Cowslip
noun

Primula veris, the European meadow primrose whose yellow flower clusters appear in late spring. The name traces to Old English cū-slyppe, cow-slop (i.e., cow dung — for where it grew). The color refers to fresh cowslip in May meadow: a soft, slightly red-shifted pale yellow with the matte finish of small five-petaled flowers in tight clusters.
