Frank Polynesia

#1f8c78
Notes

Frank Polynesia (#1F8C78) is a deep teal 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 (169°, 64%, 34%) 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

Frank
adjective

From the Old French franc, free, sincere — used as a color modifier since the seventeenth century for hues that read as direct and unhedged. Frank red, frank brown: moderate-to-high saturation combined with optical directness. Sits at the crisp-bucket alongside direct and honest.

Polynesia
noun

The vast triangle of Pacific islands — Hawaii, New Zealand, Easter Island, and the islands between. Polynesia refers to the unifying lagoon-blue-green of Polynesian atolls: a saturated, slightly cool deep blue-green with the optical clarity of warm Pacific lagoon water across thousands of cultural-cousin atolls.
