Regal Torrent Ruby

#c9174c
Notes

Regal Torrent Ruby (#C9174C) is a true red with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (342°, 79%, 44%) 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

Regal
adjective

Latin rēgālis, kingly — derived from rēx (king). As a color modifier, regal implies a saturated-and-royal-formality quality, the deep-rich color of British-Coronation-period royal vestment-and-mantle and Imperial-State-Crown regalia. Sits at the bold-and-imperial end of the grid, parallel to sovereign and royal in usage.

Torrent
modifier

Latin torrens, rushing-or-burning-stream. As a color modifier, torrent implies a rushing-and-deluge-and-flash-flood quality, the visual register of Alpine-and-Pyrenean-torrent hand-rushing-and-deluge-and-flash-flood Alpine-and-Pyrenean-torrent-and-monsoon-deluge torrent-and-rushing-and-deluge surfaces under Alpine-and-Pyrenean-torrent-and-monsoon-deluge Alpine-Dolomites-and-Pyrenean-cirque deluge-rushing-water-light. Sits at the modifier-and-weather end of the grid, parallel to rain and thaw 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.
