Voluptuous Madras

#583d9c
Notes

Voluptuous Madras (#583D9C) is a true indigo 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 (257°, 44%, 43%) 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 lime. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Voluptuous
adjective

Latin voluptuōsus, pleasurable — derived from voluptās (pleasure). As a color modifier, voluptuous implies a saturated-and-rich-and-curving-sensual quality, the deep-rich color of Rubens-and-Boucher baroque-and-rococo flesh-and-fabric tonality. Sits at the bold-and-saturated end of the grid, parallel to lush and plush in tone.

Madras
noun

Indian Coromandel Coast city (now Chennai) — once the British East India Company's premier indigo export depot, processing Bihar and Bengal Indigofera tinctoria before shipment to Europe. Madras color refers to a Madras-checked indigo-and-white cotton handloom: a saturated, slightly cool deep blue-violet with the matte finish of multi-bath fermentation indigo on hand-loomed Coromandel cotton.
