Iridescent Aspen

#cbb731
Notes

Iridescent Aspen (#CBB731) 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 (52°, 61%, 49%) 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 blue. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Iridescent
adjective

Latin Īris, rainbow — adjectival suffix -escent, named for the Greek goddess of the rainbow. As a color modifier, iridescent implies a saturated-and-multi-spectrum-shifting quality, the bright color of peacock-feather-and-soap-bubble structurally-colored-and-thin-film optical-interference patterns. Sits at the bright-and-shifting end of the grid, parallel to prismatic and holographic in usage.

Aspen
noun

Populus tremuloides, the North American quaking aspen whose leaves turn gold-yellow in autumn — the unifying fall color of Rocky Mountain landscapes. The color refers to an aspen grove at peak fall color: a saturated, slightly cool gold-yellow with the satin finish of carotenoid-rich autumn leaves. Cooler than ginkgo.
