Acidic Sake

#b4a90b
Notes

Acidic Sake (#B4A90B) 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 (56°, 88%, 37%) places it in the highly saturated band at a mid lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. 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

Acidic
adjective

Latin acidus, sour — adjectival suffix -ic, sharing root with acetic and acerbic. As a color modifier, acidic implies a saturated-and-citric-and-sour quality, the bright color of lime-zest-and-pickled-lime citrus-fruit pulp surface. Sits at the bright-and-cool end of the grid, parallel to acid and electric in usage.

Sake
noun

The Japanese rice wine — fermented from polished rice and used in religious offerings, weddings, and the kanpai toast. Sake color refers to fresh-poured junmai sake in a masu cedar box: a soft, slightly cool pale yellow with the optical clarity of grain-fermented alcohol. Cooler than mead.

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.
