Adamant Ares Brick

#c3585a
Notes

Adamant Ares Brick (#C3585A) is a true red with a warm character. It leans warm, pulling light toward red, orange, and yellow. Naturally inviting, it suits editorial and hospitality contexts. Its HSL profile (359°, 47%, 55%) 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

Adamant
adjective

Greek adámas, unconquerable — derived from a- (not) plus damnan (to subdue). As a color modifier, adamant implies a saturated-and-rock-hard quality where the hue maintains diamond-hard pigmentation. Sits at the bold-and-resilient end of the grid, parallel to indomitable and ironclad in usage.

Ares
modifier

Greek Ἄρης, god-of-war. As a color modifier, ares implies a war-god-and-iron-and-blood quality, the visual register of Olympian-Ares-and-Spartan-temple-Ares hand-war-god-and-iron-and-blood Olympian-Ares-and-Spartan-temple-and-Areopagus ares-and-war-god-and-iron-and-blood surfaces under Olympian-Ares-and-Spartan-temple-and-Areopagus Athenian-Acropolis-and-rocky-outcrop war-god-light. Sits at the modifier-and-myth end of the grid, parallel to zeus and atlas 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.
