Resolute Mull Ruby

#ce1845
Notes

Resolute Mull Ruby (#CE1845) is a true red with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (345°, 79%, 45%) places it in the highly saturated band at a mid 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

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.

Mull
modifier

Middle English mullen, to-grind-or-ponder. As a color modifier, mull implies a slow-pondered-and-warmed-and-spiced quality, the visual register of mulled-wine-and-mulled-thought hand-slow-pondered-and-warmed-and-spiced mulled-wine-and-mulled-cider-and-mulled-thought mulled-and-slow-pondered-and-warmed-and-spiced surfaces under mulled-wine-and-mulled-cider-and-mulled-thought clove-and-cinnamon-and-orange-peel hearth-side-winter-light. Sits at the modifier-and-mood end of the grid, parallel to muse and brood 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.
