Homemade Obsidian

#03000c
Notes

Homemade Obsidian (#03000C) 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 (255°, 100%, 2%) 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 lime. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Homemade
adjective

English compound home + past-participle made — sharing root with make. As a color modifier, homemade implies a neutral-and-handcrafted-and-domestic quality, the neutral color of American-and-English-cottage hand-made-and-home-craft household-textile-and-pottery surface-finish. Sits at the neutral-and-traditional end of the grid, parallel to handmade and handcrafted in usage.

Obsidian
noun

Volcanic glass — molten rhyolite cooled too quickly to crystallize. Mined since the Stone Age for blade-edges (sharper than surgical steel) and ground into mirrors by the Aztec priesthood for divination. The color refers to a polished obsidian flake from Mount Hekla or Glass Buttes, Oregon: a deep, slightly blue-shifted black with the high-gloss conchoidal fracture of natural glass. Cooler than onyx, glossier than coal.
