Frank Maui

#37ba9a
Notes

Frank Maui (#37BA9A) 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 (165°, 54%, 47%) 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

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.

Maui
noun

The Hawaiian island — and the saturated turquoise of Maui's Molokini Crater snorkeling-lagoon water. Maui refers to Molokini Crater at midday: a saturated, slightly cool deep blue-green with the optical clarity of cold Pacific water filtered through volcanic black-sand and white coral.
