Confident Anise Ruby

#a21e1f
Notes

Confident Anise Ruby (#A21E1F) 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 (360°, 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

Confident
adjective

A late-Latin participle, confidens, trusting — borrowed into English in the sixteenth century. As a color modifier, confident implies saturation combined with poise: a confident red doesn't try too hard, just sits at the level of its hue without overreaching. Sits in the bold-bucket center near bold and resolute.

Anise
modifier

Latin anīsum, sweet-licorice-seed. As a color modifier, anise implies a sweet-licorice-and-Mediterranean-aniseed quality, the visual register of Sicilian-and-Provençal-anise hand-sweet-licorice-and-Mediterranean-aniseed Sicilian-and-Provençal-anise-and-Pernod-Ricard anise-and-sweet-licorice surfaces under Sicilian-and-Provençal-anise-and-Pernod-Ricard Marseille-and-Sicily-and-Pastis Mediterranean-licorice-light. Sits at the modifier-and-flavor end of the grid, parallel to clove and caraway 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.
