Solid Oriole

#bb3713
Notes

Solid Oriole (#BB3713) 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 (13°, 82%, 40%) 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 cyan. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Solid
adjective

Latin solidus, firm, dense — used as a color modifier since the seventeenth century for hues that read as continuous and unbroken: a solid blue is one with no variation across the surface. Implies high saturation combined with optical density. Sits in the bold-bucket alongside strong and robust, slightly more focused on uniformity.

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.
