Robust Goa

#810369
Notes

Robust Goa (#810369) is a deep 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 (311°, 95%, 26%) 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

Robust
adjective

From the Latin robustus, of oak — implying strength combined with substance. As a color modifier, robust describes saturation combined with body: a robust burgundy, a robust olive. Sits in the bold-and-warm corner alongside strong and solid, with the slightly textural implication of a color that has substance behind the pigment.

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.

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.
