Refulgent Zafarani

#ecb428
Notes

Refulgent Zafarani (#ECB428) is a true amber with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (43°, 84%, 54%) places it in the highly saturated band at a mid lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. For a confident two-color system, pair it with its complementary azure. 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.

Zafarani
noun

The Persian word for saffron-colored — used for the warm yellow-orange of zafarani-čubeh and the saffron-dyed silk of Safavid court robes. The color refers to zafarani-dyed silk: a saturated, slightly red-shifted gold-yellow with the satin finish of plant-dyed silk. Warmer than saffron, deeper than zard.

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.
