Resolute Stalk Ruby

#93141b
Notes

Resolute Stalk Ruby (#93141B) 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 (357°, 76%, 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 cyan. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Resolute
adjective

From the Latin resolutus, unwavering — used as a color modifier in literary contexts for hues that read as committed and unmoving. Resolute blue, resolute green: the saturation is full, the hue holds its position without shifting under different light. Sits in the bold-bucket center alongside strong and true, with slightly more focus on stability than presence.

Stalk
modifier

Old English stealcung, to-walk-stealthily. As a color modifier, stalk implies a deliberate-and-stealthy-and-tracked quality, the visual register of Highland-stalker-and-stag-stalk hand-deliberate-and-stealthy-and-tracked Highland-stalker-and-stag-and-tracker stalked-and-deliberate-and-stealthy-and-tracked surfaces under Highland-stalker-and-stag-and-tracker heather-moor-and-corrie-and-deer-forest tracked-and-stealthy-light. Sits at the modifier-and-mood end of the grid, parallel to prowl and creep 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.
