Grounded Zhusha

#d81011
Notes

Grounded Zhusha (#D81011) is a true red with a neon character. It sits at the high-saturation edge of its family. Use it sparingly, as signage, accent, or highlight against darker surfaces. Its HSL profile (360°, 86%, 45%) 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

Grounded
adjective

Old English grund, bottom / foundation — past-participle of ground. As a color modifier, grounded implies a saturated-and-foundational quality where the hue anchors the surrounding palette through its weighty presence. Sits at the bold-and-balanced end of the grid, parallel to centered and anchored.

Zhusha
noun

The Chinese name for cinnabar — mercury sulfide — ground into the imperial-seal pigment used in Chinese painting, lacquerware, and the carved cinnabar-lacquer ornaments of the Ming dynasty. The color refers to a freshly stamped zhusha seal on rice paper: a saturated, slightly orange red with the matte finish of fine mineral pigment. Cooler than vermillion, brighter than crimson.
