Torrid Buttercup

#a09b1d
Notes

Torrid Buttercup (#A09B1D) is a true yellow 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 (58°, 69%, 37%) 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

Torrid
adjective

Latin torridus, parched / scorching — sharing root with torrēre (to dry by heat). As a color modifier, torrid implies a saturated-and-tropical-hot quality, the bright color of equatorial-Saharan-and-Sonoran-desert mid-summer high-temperature surface-emission. Sits at the bright-and-warm end of the grid, parallel to scorching and fiery in usage.

Buttercup
noun

Ranunculus acris and its meadow cousins — the small, glossy yellow flowers of European pastures whose petals reflect ultraviolet light to attract bees. The color refers to a buttercup petal in full sun: a saturated, slightly cool yellow with the polished finish of an epidermis that scatters light like wet paint. The folk test for whether you like butter — holding the flower under your chin to catch its yellow reflection — works on every variety.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
