Grounded Waft Ruby

#a51121
Notes

Grounded Waft Ruby (#A51121) 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 (354°, 81%, 36%) 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

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.

Waft
modifier

Middle English waft, related to wafian, to-wave-in-air. As a color modifier, waft implies a gently-conveyed-and-air-borne-and-drifting quality, the visual register of incense-and-rose-petal-waft hand-gently-conveyed-and-air-borne-and-drifting incense-and-rose-petal-and-summer-curtain wafted-and-gently-conveyed-and-air-borne surfaces under incense-and-rose-petal-and-summer-curtain church-thurible-and-walled-rose-garden-and-open-window airborne-drift-light. Sits at the modifier-and-mood end of the grid, parallel to drift and mist in usage.

Ruby
noun

From the Latin ruber — simply, red. The gemstone is a chromium-tinged corundum, harder than anything in nature except diamond, and so saturated that a fine Burmese pigeon's blood ruby at auction outpaces a comparable diamond by weight. The color borrows the gem's confidence: a clear, glassy red without the brown of garnet or the blue of crimson.

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.
