Bleak Anodorhynchus

#151c5c
Notes

Bleak Anodorhynchus (#151C5C) is a deep blue 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 (234°, 63%, 22%) 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 amber. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Bleak
adjective

Old Norse bleikr, pale — sharing root with English bleach. As a color modifier, bleak implies a deep-and-cold-and-comfortless quality, the dark gray-pale of Yorkshire-Moors and Hebrides late-winter atmospheric-light. Sits at the deep-and-cool end of the grid, parallel to grim and bitter in atmospheric register.

Anodorhynchus
noun

The genus Anodorhynchus — particularly A. hyacinthinus (hyacinth macaw), the largest of all parrot species, native to central South America. The plumage is the most saturated true blue of any parrot. The color refers to a male A. hyacinthinus in adult plumage: a saturated, slightly cool deep blue with the matte finish of structurally-and-pigment-colored macaw feathers.
