Imperial Madagascar

#418b28
Notes

Imperial Madagascar (#418B28) 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 (105°, 55%, 35%) 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

Imperial
adjective

From the Latin imperialis, of the empire — applied to color since the medieval period for the hues reserved for sovereigns and empires: imperial purple of Tyrian dye, imperial yellow of Ming-dynasty porcelain. As a modifier, imperial implies saturation combined with the institutional weight of a color owned by a court. Sits in the bold-and-deep corner, alongside royal.

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.
