Unwavering Oriole

#ac4a33
Notes

Unwavering Oriole (#AC4A33) is a true red with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (11°, 54%, 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

Unwavering
adjective

Old English un- (negation) plus wafrian (to flicker). As a color modifier, unwavering implies a saturated-and-constant quality where the hue maintains its full strength without flicker or shift. Sits at the bold-and-firm end of the grid, parallel to steadfast and firm in usage.

Oriole
noun

The genus Icterus — particularly I. galbula, the Baltimore oriole whose males in breeding plumage are vivid orange with black wings. The color refers to a male Baltimore oriole at full breeding plumage: a saturated, slightly cool orange with the matte finish of carotenoid-pigmented feathers. Brighter than tangerine, warmer than carrot.

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.
