Resonant Waft Ruby

#a61829
Notes

Resonant Waft Ruby (#A61829) 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 (353°, 75%, 37%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. 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

Resonant
adjective

Latin resonāns, echoing — present-participle of resonate, sharing root with sonance. As a color modifier, resonant implies a saturated-and-deep-vibrating quality where the hue carries low-frequency visual richness. Sits at the bold-and-resonant end of the grid, parallel to sonorous and resounding in usage.

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.
