Opulent Watermelon

#913a78
Notes

Opulent Watermelon (#913A78) is a true magenta 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 (317°, 43%, 40%) 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 green. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Opulent
adjective

Latin opulentus, rich / wealthy — derived from ops (wealth). As a color modifier, opulent implies a saturated-and-luxurious quality, the deep-rich color of Belle-Époque and Gilded-Age interior-decoration silk-and-velvet textiles. Sits at the bold-and-saturated end of the grid, parallel to lavish and sumptuous.

Watermelon
noun

Citrullus lanatus, the African cucurbit cultivated for at least four thousand years for its high-water-content red flesh. The color refers to the cross-section of a ripe watermelon's interior: a saturated, slightly cool deep pink-red with the optical brightness of high-water-content fruit pigmented by lycopene. Cooler than coral, warmer than salmon, with the summer-cookout weight of a fruit that gives English a synonym for unripe-pink.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
