Authoritative Goa

#ab158c
Notes

Authoritative Goa (#AB158C) is a true magenta 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 (312°, 78%, 38%) 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 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.

Goa
noun

Indian Konkan-coast state — once a Portuguese colonial outpost (1510–1961) whose churches, fish-market stalls, and saris carry the gulābi deep-magenta of bandhani tie-dyed cotton. Goa color refers to a bandhani-tied magenta sari at a Goa fish-market stall: a saturated, slightly cool deep magenta with the matte finish of natural-dye-and-resist-tied cotton. Warmer than Bengali neel.

Wide gamut

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.
