Frank Goldfinch

#634314
Notes

Frank Goldfinch (#634314) is a deep amber 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 (36°, 66%, 23%) 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 azure. For something softer, pull in its analogous neighbors on either side of the wheel.

Goldfinch
noun

Carduelis carduelis, the European goldfinch whose male plumage features bright yellow wing bars and a red face mask. The color refers to the yellow wing bar of a fresh-molted goldfinch: a saturated, slightly red yellow with the matte finish of carotenoid-pigmented feathers. Brighter than canary.
