Looming Madras

#311269
Notes

Looming Madras (#311269) is a deep indigo 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 (261°, 71%, 24%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. 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

Looming
adjective

Middle English lomen, to appear vaguely — present-participle of loom. As a color modifier, looming implies a deep-and-vague-and-imposing quality, the dark cool-gray of fog-veiled-and-distant cliff-or-mountain-mass against the sky. Sits at the deep-and-imposing end of the grid, parallel to imposing and towering.

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.
