Opulent Vela Ruby

#971b1a
Notes

Opulent Vela Ruby (#971B1A) 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 (0°, 71%, 35%) 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 cyan. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Opulent
adjective

Latin opulentus, rich / wealthy — derived from ops (wealth). As a color modifier, opulent implies a saturated-and-luxurious quality, the deep-rich color of Belle-Époque and Gilded-Age interior-decoration silk-and-velvet textiles. Sits at the bold-and-saturated end of the grid, parallel to lavish and sumptuous.

Vela
modifier

Latin vela, sails-of-the-Argo. As a color modifier, vela implies a southern-hemisphere-and-Argo-sail-and-supernova-remnant quality, the visual register of Vela-supernova-remnant-and-Argo-sails hand-southern-hemisphere-and-Argo-sail-and-supernova-remnant Vela-supernova-remnant-and-Argo-sails-and-southern-Milky-Way vela-and-southern-hemisphere-and-Argo-sail surfaces under Vela-supernova-remnant-and-Argo-sails-and-southern-Milky-Way Southern-Cross-and-southern-zenith southern-stellar-light. Sits at the modifier-and-cosmic end of the grid, parallel to cygnus and draco 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.
