Spartan Taurus Brick

#ac3f24
Notes

Spartan Taurus Brick (#AC3F24) 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 (12°, 65%, 41%) 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

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.

Taurus
modifier

Latin taurus, bull-of-the-zodiac. As a color modifier, taurus implies a bull-and-earth-sign-and-Venus-ruled-fixed-earth quality, the visual register of Mesopotamian-bull-and-Greek-Taurus hand-bull-and-earth-sign-and-Venus-ruled-fixed-earth Mesopotamian-bull-and-Greek-Taurus-and-Pleiades-cluster taurus-and-bull-and-earth-sign surfaces under Mesopotamian-bull-and-Greek-Taurus-and-Pleiades-cluster spring-and-April-and-May fixed-earth-sign-light. Sits at the modifier-and-zodiac end of the grid, parallel to aries and gemini in usage.

Brick
noun

Fired clay, mineral red. The color refers to common building brick — iron-rich earthenware kilned to the specific dusky red-orange of a Victorian terrace, a Roman aqueduct, an adobe wall in New Mexico. Less saturated than ruby, warmer than burgundy, with a chalky cast that reads as architectural rather than decorative.

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.
