Bold Hyssop Ruby

#9a0720
Notes

Bold Hyssop Ruby (#9A0720) 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 (350°, 91%, 32%) 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.

Hyssop
modifier

Hebrew ēzōb, Biblical-purifying-herb. As a color modifier, hyssop implies a Biblical-purifying-herb-and-monastic-physic-garden quality, the visual register of monastic-physic-garden-and-Biblical-hyssop hand-Biblical-purifying-herb-and-monastic-physic-garden monastic-physic-garden-and-Biblical-hyssop-and-Cluniac-cloister hyssop-and-Biblical-purifying-herb surfaces under monastic-physic-garden-and-Biblical-hyssop-and-Cluniac-cloister Cluny-and-Saint-Gall-physic-garden monastic-physic-light. Sits at the modifier-and-flavor end of the grid, parallel to savory and balm 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.
