Authoritative Kansas

#8a930f
Notes

Authoritative Kansas (#8A930F) is a deep 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 (64°, 81%, 32%) places it in the highly saturated band at a dark 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

Authoritative
adjective

Latin auctōritāt-, authority — adjectival suffix -ive. As a color modifier, authoritative implies a saturated-and-formal-imperative quality where the hue carries decisional weight and institutional credibility. Sits at the bold-and-authoritative end of the grid, parallel to commanding and magisterial in usage.

Kansas
noun

The American Midwestern state — and the yellow of Kansas wheat at harvest, sunflower fields (Kansas is the Sunflower State), and the Yellow Brick Road of The Wonderful Wizard of Oz. Kansas refers to a Kansas wheat field at midsummer: a soft, slightly muted warm yellow-tan with the matte finish of ripening grain.
