Welcoming Bayou

#105a7c
Notes

Welcoming Bayou (#105A7C) is a deep cyan 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 (199°, 77%, 27%) 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 orange. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Welcoming
adjective

Old English wel-cuman, well-coming — present-participle of welcome. As a color modifier, welcoming implies a clear-and-inviting-and-warm quality where the hue carries the visual register of cordial-and-hospitable color-tone. Sits at the crisp-and-cheerful end of the grid, parallel to hospitable and inviting in usage.

Bayou
noun

A slow-moving body of water in the Mississippi-Louisiana wetland — particularly the Atchafalaya Basin and Cajun Country swamps. Bayou color refers to typical Louisiana bayou water: a soft, slightly cool deep blue-green with the optical complexity of tannin-stained slow-moving freshwater under cypress canopy.

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.
