Smooth Caribbean

#255a4a
Notes

Smooth Caribbean (#255A4A) is a deep teal 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 (162°, 42%, 25%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. For a confident two-color system, pair it with its complementary red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Smooth
adjective

Old English smōþ, level, polished — used as a color modifier since the seventeenth century for hues that read as continuous without texture or break. Smooth tan, smooth gray: moderate saturation combined with optical evenness. Sits in the crisp-bucket alongside even.

Caribbean
noun

The Caribbean Sea — the tropical basin between the Gulf of Mexico and the Atlantic, ringed by Cuba, Hispaniola, the Lesser Antilles, and the Central American mainland. The color refers to mid-depth Caribbean water on a sunny day: a saturated, slightly muted blue-green with the optical complexity of pure water filtered through coral sand. Cooler than turquoise, warmer than azure, with the postcard weight of a sea named for its indigenous people.
