Bright Tortilla

#a4ad05
Notes

Bright Tortilla (#A4AD05) 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 (63°, 94%, 35%) 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

Bright
adjective

Old English beorht, shining, luminous — cognate with the German Bracht, splendor. Applied to color since at least the medieval period for hues that read as luminous: not just light in value but optically active, as if scattering more light back than a dimmer color of the same lightness would. Sits at the bright-bucket center alongside vivid and brilliant.

Tortilla
noun

The Mexican corn flatbread — the staple grain of Mesoamerican civilization since pre-Columbian times. Tortilla color refers to the warm pale yellow of fresh-pressed maize tortillas: a soft, slightly red-shifted warm pale yellow with the matte finish of cooked masa. Cooler than polenta.
