Majestic Madagascar

#188d00
Notes

Majestic Madagascar (#188D00) is a deep green with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (110°, 100%, 28%) places it in the highly saturated band at a dark lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. 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

Majestic
adjective

Latin māiestātis, majesty — adjectival suffix -ic. As a color modifier, majestic implies a saturated-and-imposing-grandeur quality, the deep-rich color of Salisbury-Cathedral-and-Chartres-Cathedral Gothic-architecture monumental presence against the open sky. Sits at the bold-and-imposing end of the grid, parallel to regal and imperial.

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.

Display P3 representation

The CSS Color 4 wide-gamut form of this color. Both swatches render the same color on every display — the P3 form only diverges from sRGB when a designer pushes channels outside sRGB's reach.

This color is chromatic enough that authoring it as P3 native (instead of clamping to sRGB) gives a perceptibly more saturated render on wide-gamut displays — modern Macs, iPhones, iPads, and most recent OLED laptops.
