Spartan Odin Ruby

#8b0415
Notes

Spartan Odin Ruby (#8B0415) 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 (352°, 94%, 28%) 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

Spartan
adjective

Greek Spartiátēs, of Sparta — adjectival suffix referring to the Lacedaemonian warrior city. As a color modifier, spartan implies a saturated-and-disciplined-and-formal quality, the deep-rich color of Spartan-hoplite military-class crimson-and-bronze armor-and-cloak. Sits at the bold-and-formal end of the grid, parallel to austere and stern in tone.

Odin
modifier

Old Norse Óðinn, all-father-of-the-Aesir. As a color modifier, odin implies a one-eyed-and-raven-and-runic-wisdom quality, the visual register of Norse-all-father-Odin-and-Yggdrasil hand-one-eyed-and-raven-and-runic-wisdom Norse-all-father-Odin-and-Yggdrasil-and-Asgard odin-and-one-eyed-and-raven-and-runic-wisdom surfaces under Norse-all-father-Odin-and-Yggdrasil-and-Asgard Hugin-and-Munin-raven-and-Mimir-well runic-wisdom-light. Sits at the modifier-and-myth end of the grid, parallel to thor and freya 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.
