Utilitarian Rarotonga

#38b1a4
Notes

Utilitarian Rarotonga (#38B1A4) is a true 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 (174°, 52%, 46%) 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 red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Utilitarian
adjective

Latin ūtilitās, usefulness — adjectival suffix -ian. As a color modifier, utilitarian implies a clear-and-purpose-fit-and-stripped-down quality, the crisp color of Shaker-and-Quaker anti-ornamental functional-and-no-frills craft tradition. Sits at the crisp-and-functional end of the grid, parallel to functional and workmanlike in usage.

Rarotonga
noun

The largest island of the Cook Islands — and the saturated turquoise of Muri Lagoon at Rarotonga's eastern shore. Rarotonga color refers to Muri Lagoon at midday: a saturated, slightly cool deep blue-green with the optical clarity of warm Pacific lagoon water.
