Courteous Grackle

#140411
Notes

Courteous Grackle (#140411) is a deep magenta 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 (311°, 67%, 5%) 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 green. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Courteous
adjective

Old French cortois, of-the-court — adjectival suffix -ous. As a color modifier, courteous implies a neutral-and-formal-and-polite quality where the hue carries the visual register of Edwardian-and-Belle-Époque formal-and-courteous-of-the-court interior-decoration-and-dress-attire coordinated-color tone. Sits at the neutral-and-friendly end of the grid, parallel to mannerly and polite 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.
