Buttoned Oro

#b38728
Notes

Buttoned Oro (#B38728) is a true amber with a warm character. It leans warm, pulling light toward red, orange, and yellow. Naturally inviting, it suits editorial and hospitality contexts. Its HSL profile (41°, 63%, 43%) places it in the balanced 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 azure. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Buttoned
adjective

Old French bouton, button — past-participle of button. As a color modifier, buttoned implies a clear-and-fastened-and-formal quality, the crisp color of Edwardian-period formal-attire fully-fastened-and-formally-dressed gentleman's-attire. Sits at the crisp-and-finished end of the grid, parallel to trim and pressed in usage.

Oro
noun

The Spanish and Italian word for gold — used in heraldic vocabulary, religious art, and fashion for the metallic warm yellow of Renaissance gilding. The color refers to a freshly gilded Spanish altarpiece: a saturated, slightly cool deep gold with the metallic finish of beaten gold leaf. The Romance-language cousin of jīn and kogane.
