Bold Athens Ruby

#9b0f22
Notes

Bold Athens Ruby (#9B0F22) 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°, 82%, 33%) 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

Bold
adjective

Old English beald, brave, courageous — a quality word that crossed over to color in the late seventeenth century. Bold describes a color that asserts itself: high saturation combined with mid lightness, where the hue presents itself without compromise. Sits at the center of the bold-bucket grid, near strong and rich. Closer to a presence word than a pigment word.

Athens
modifier

Greek Ἀθῆναι, Athens. As a color modifier, athens implies an Acropolis-and-philosophical-city-state quality, the visual register of Athenian-Classical-City-State hand-built Acropolis-and-Parthenon-and-marble-temple-and-pottery Doric-and-Ionic-and-Corinthian surfaces under Athenian-Acropolis-and-Parthenon classical Aegean-marble-temple light. Sits at the modifier-and-cultural end of the grid, parallel to sparta and greek 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.
