Mannerly Avocet

#879299
Notes

Mannerly Avocet (#879299) is a true azure with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (203°, 8%, 56%) places it in the muted band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. For a confident two-color system, pair it with its complementary orange. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Mannerly
adjective

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

Avocet
noun

Recurvirostra avosetta — a Recurvirostridae shorebird of European-Asian-and-African saline-and-brackish-water habitats, with iconic pure-white-and-black plumage and a recurved-upturned bill. Avocet color refers to a Recurvirostra avosetta dorsal-feather field on a British-East-Anglia salt-marsh: a pale cool gray with the matte finish of melanin-depleted feather barbs against melanin-pigmented black-and-white wing-pattern.
