Refulgent Maui

#37ba8c
Notes

Refulgent Maui (#37BA8C) 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 (159°, 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 magenta. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Refulgent
adjective

Latin refulgēns, shining-back — present-participle of refulgere, sharing root with fulgor (lightning). As a color modifier, refulgent implies a saturated-and-reflective-shining quality, the bright color of polished-bronze-and-armor reflective-surface mid-day-sun reflection. Sits at the bright-and-saturated end of the grid, parallel to effulgent and resplendent in usage.

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.
