Radiant Yolk
Radiant Yolk (#A5A914) is a true yellow with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (62°, 79%, 37%) 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 blue. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
From the Latin radiare, to emit rays — used as a color word since the seventeenth century for hues that read as luminous and emitting. Radiant gold, radiant pink: the implication is high luminance combined with the optical impression of an outward light. Sits in the bright-bucket center alongside glowing.
The yellow center of a chicken egg — colored by carotenoid pigments in the hen's feed, ranging from pale lemon (commercial barn-raised) to deep orange (pasture-raised, marigold-supplemented). The color refers to a fresh free-range yolk against the white: a saturated, slightly orange-shifted yellow with the satiny surface of a vitellus membrane. Warmer than canary, deeper than sunflower; the unifying yellow of breakfast.
