Pure Peplos Ruby

#a2221e
Notes

Pure Peplos Ruby (#A2221E) is a true 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 (2°, 69%, 38%) 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

Pure
adjective

Latin purus, clean, unmixed — applied to color since antiquity for hues that contain only one pigment without dilution by white, black, or another color. Pure red is the textbook ideal: high saturation, mid lightness, no shift. Sits at the bold-bucket center, parallel to true and strong.

Peplos
modifier

Greek πέπλος, Hellenic-women's-robe. As a color modifier, peplos implies a Hellenic-women's-peplos-and-pinned-shoulder quality, the visual register of Hellenic-peplos-and-Athena-Parthenos hand-Hellenic-women's-peplos-and-pinned-shoulder Hellenic-peplos-and-Athena-Parthenos-and-Panathenaic-festival peplos-and-Hellenic-women's-peplos surfaces under Hellenic-peplos-and-Athena-Parthenos-and-Panathenaic-festival Athenian-Acropolis-and-Panathenaic-procession Hellenic-court-light. Sits at the modifier-and-textile end of the grid, parallel to chiton and tunic 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.
