Smoldering Awe Ruby

#b83b28
Notes

Smoldering Awe Ruby (#B83B28) is a true red with a warm character. It leans warm, pulling light toward red, orange, and yellow. Naturally inviting, it suits editorial and hospitality contexts. Its HSL profile (8°, 64%, 44%) 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

Smoldering
adjective

The progressive participle of smolder, to burn slowly without flame. Used as a color word since the late nineteenth century for the deep reds and oranges of barely-flame coal — the warm saturated darks where the heat is internal rather than emitted. Sits in the bold-and-warm corner, slightly less luminous than burning and slightly less calm than rich.

Awe
modifier

Old Norse agi, fright-and-reverence. As a color modifier, awe implies a reverent-and-overwhelmed-and-hushed quality, the visual register of Burkean-sublime-and-Caspar-David-Friedrich-awe hand-reverent-and-overwhelmed-and-hushed Burkean-sublime-and-Caspar-David-Friedrich-and-Romantic-vista awed-and-reverent-and-overwhelmed-and-hushed surfaces under Burkean-sublime-and-Caspar-David-Friedrich-and-Romantic-vista alpine-and-storm-cloud-and-mountain-pass cathedral-of-nature-light. Sits at the modifier-and-mood end of the grid, parallel to bliss and grace 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.
