Voluptuous Fei

#a30f2b
Notes

Voluptuous Fei (#A30F2B) is a true red 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 (349°, 83%, 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 teal. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Voluptuous
adjective

Latin voluptuōsus, pleasurable — derived from voluptās (pleasure). As a color modifier, voluptuous implies a saturated-and-rich-and-curving-sensual quality, the deep-rich color of Rubens-and-Boucher baroque-and-rococo flesh-and-fabric tonality. Sits at the bold-and-saturated end of the grid, parallel to lush and plush in tone.

Fei
noun

A bright, slightly cool red used in Chinese textile tradition for the inner robes of Tang-dynasty court officials. The color refers to a fei-dyed silk: a saturated, slightly cool red with the satin finish of plant-dye-on-silk. Cooler than hong, brighter than jiang. The Chinese cousin of karakurenai.
