Authoritative Yucatan

#a7058e
Notes

Authoritative Yucatan (#A7058E) is a deep violet 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 (309°, 94%, 34%) 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 green. 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.

Yucatan
noun

Mexican peninsula, the limestone Karst shelf of southern Mexico — home of the Pink Lakes of Las Coloradas (deep magenta saline waters colored by halophilic algae and brine shrimp). Yucatan color refers to a Las Coloradas Pink Lake surface in midday sun: a saturated, slightly cool deep magenta with the matte finish of halophilic-algae-and-brine-shrimp-tinted hyper-saline water. The lakes are also a Phoenicopterus ruber flamingo nesting site.

Display P3 representation

The CSS Color 4 wide-gamut form of this color. Both swatches render the same color on every display — the P3 form only diverges from sRGB when a designer pushes channels outside sRGB's reach.

This color is chromatic enough that authoring it as P3 native (instead of clamping to sRGB) gives a perceptibly more saturated render on wide-gamut displays — modern Macs, iPhones, iPads, and most recent OLED laptops.
