Homemade Grackle

#180331
Notes

Homemade Grackle (#180331) 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 (267°, 88%, 10%) 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.

Grackle
noun

North American Quiscalus genus — Icteridae family blackbirds with deep-iridescent-blue-purple-bronze plumage, particularly the common grackle (Q. quiscula) of midwestern-and-eastern grasslands. Grackle color refers to a Quiscalus quiscula breeding-male nape-feather field in raking late-summer light: a saturated, slightly cool deep black with the iridescent satin finish of structurally colored feather barbs.
