Shimmering Fei
Shimmering Fei (#F86471) is a true red 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 (355°, 91%, 68%) 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 cyan. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Old English scimerian, to glisten — present-participle of shimmer, sharing root with shine. As a color modifier, shimmering implies a saturated-and-soft-flicker-reflective quality, the bright color of moonlit-water-and-silken-fabric surface-reflection. Sits at the bright-and-reflective end of the grid, parallel to glistening and glimmering in usage.
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.
