Sumptuous Madagascar

#428f27
Notes

Sumptuous Madagascar (#428F27) is a true green with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (104°, 57%, 36%) 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 violet. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Sumptuous
adjective

Latin sūmptuōsus, expensive — derived from sūmptus (expense). As a color modifier, sumptuous implies a saturated-and-rich-and-luxurious quality, the deep-rich color of Burgundy-and-Champagne-Court late-medieval silk-and-velvet livery in the Très-Riches-Heures manuscript tradition. Sits at the bold-and-saturated end of the grid, parallel to opulent and lavish.

Madagascar
noun

The Indian Ocean island — and the saturated deep green of Madagascan rainforest, home to most of the world's lemur species. Madagascar color refers to an Andasibe-Mantadia canopy: a saturated, slightly cool deep yellow-green with the matte finish of mid-altitude tropical forest.
