Homey Pleonaste

#0a0120
Notes

Homey Pleonaste (#0A0120) 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 (257°, 94%, 6%) 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

Homey
adjective

Old English hām, home — adjectival suffix -y. As a color modifier, homey implies a neutral-and-comfortable-and-domestic quality, the neutral color of American-and-English-cottage domestic-and-everyday hand-spun-and-comfortable interior-and-textile-finish surface. Sits at the neutral-and-traditional end of the grid, parallel to homespun and folksy in usage.

Pleonaste
noun

Mg(Al,Fe)₂O₄ iron-rich black spinel — a deep-black variety of the spinel group, mined principally at Vesuvius in Italy and at Långban in Sweden. Pleonaste color refers to a freshly cleaved Vesuvius pleonaste octahedral crystal face: a saturated, slightly cool deep black with the glassy finish of cubic-system magnesium-iron-aluminum-oxide. The Greek genus name pleonasmós (excess) refers to its many cleavage-faces.
