Centered Shu

#9a052d
Notes

Centered Shu (#9A052D) is a deep 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 (344°, 94%, 31%) places it in the highly saturated band at a dark 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

Centered
adjective

Latin centrum, center — past-participle of center. As a color modifier, centered implies a saturated-and-grounded-and-balanced quality where the hue occupies the visual center of its palette without drift. Sits at the bold-and-balanced end of the grid, parallel to poised and grounded.

Shu
noun

Vermillion in Japanese — specifically the cinnabar-derived pigment used since the Heian period to paint Shinto torii gates, temple beams, and the lacquer of imperial seals. The color refers to a freshly painted Inari Shrine torii: a saturated, slightly orange red with the high gloss of layered urushi lacquer. Brighter than crimson, deeper than tangerine, with the sacred-architectural weight of a color reserved for thresholds between human and divine.

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.
