Wellbred Ishtar Ruby

#a10d23
Notes

Wellbred Ishtar Ruby (#A10D23) is a deep 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 (351°, 85%, 34%) places it in the highly saturated band at a dark 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

Wellbred
adjective

Old English wel-brēd, well-bred — past-participle of breed, sharing root with brood (offspring). As a color modifier, wellbred implies a saturated-and-elegant-and-formal quality, the deep-rich color of Edwardian-period finishing-school-and-debutante-Court English-aristocratic livery. Sits at the bold-and-elegant end of the grid, parallel to highborn and patrician.

Ishtar
modifier

Akkadian Ištar, Babylonian-goddess-of-love-and-war. As a color modifier, ishtar implies a Babylonian-Venus-and-eight-pointed-star quality, the visual register of Babylonian-Ishtar-Gate-and-Mesopotamian-temple hand-Babylonian-Venus-and-eight-pointed-star Babylonian-Ishtar-Gate-and-Mesopotamian-temple-and-Akkadian-cylinder-seal ishtar-and-Babylonian-Venus-and-eight-pointed-star surfaces under Babylonian-Ishtar-Gate-and-Mesopotamian-temple-and-Akkadian-cylinder-seal Babylon-and-Nineveh-and-Mari blue-glazed-brick-light. Sits at the modifier-and-myth end of the grid, parallel to isis and hera 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.
