Refulgent Witchhazel

#b1c430
Notes

Refulgent Witchhazel (#B1C430) 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 (68°, 61%, 48%) 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

Refulgent
adjective

Latin refulgēns, shining-back — present-participle of refulgere, sharing root with fulgor (lightning). As a color modifier, refulgent implies a saturated-and-reflective-shining quality, the bright color of polished-bronze-and-armor reflective-surface mid-day-sun reflection. Sits at the bright-and-saturated end of the grid, parallel to effulgent and resplendent in usage.

Witchhazel
noun

Hamamelis virginiana, the North American shrub whose distinctive yellow ribbon-petaled flowers bloom in late autumn — and whose bark and leaves yield the astringent witch hazel extract. The color refers to a fresh Hamamelis bloom in November: a saturated, slightly red yellow with the satin finish of crinkled-ribbon petal.

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.
