Effulgent Maui
Effulgent Maui (#3EAF57) is a true green 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 (133°, 48%, 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 magenta. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Latin effulgēns, shining-out — present-participle of effulgere, sharing root with fulgor (lightning). As a color modifier, effulgent implies a saturated-and-radiating-light-out quality, the bright color of Renaissance-Madonna halo-and-aureole gold-leaf-and-pigment emission. Sits at the bright-and-saturated end of the grid, parallel to resplendent and radiant in usage.
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.
