Sterile Bahamas

#2389b5
Notes

Sterile Bahamas (#2389B5) is a true cyan with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (198°, 68%, 42%) 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 orange. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Sterile
adjective

Latin sterilis, barren / not-fertile — sharing root with Greek steiros (barren). As a color modifier, sterile implies a clear-and-medical-clean-and-stripped quality, the crisp color of operating-theater surgical-environment white-and-stainless-steel surfaces. Sits at the crisp-and-clean end of the grid, parallel to sanitary and hygienic in usage.

Bahamas
noun

The Atlantic archipelago — and the saturated turquoise of Bahamian Pink Sands Beach shallows at Harbour Island and the cyan-blue of Exuma Cays lagoon water. Bahamas color refers to a Bahamian shallow-water lagoon at midday: a saturated, slightly cool bright blue-green with the optical clarity of warm Caribbean water.

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.
