Dominant Roseate

#990175
Notes

Dominant Roseate (#990175) 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 (314°, 99%, 30%) 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

Dominant
adjective

Latin dominārī, to rule — present-participle of dominate. As a color modifier, dominant implies a saturated-and-leading quality where the hue claims visual precedence over neighboring colors in the surrounding palette. Sits at the bold-and-imperative end of the grid, parallel to commanding and authoritative.

Roseate
noun

Latin rosātus, rosy — adopted into English for any naturally pink-magenta colored phenomenon, particularly the roseate spoonbill (Platalea ajaja) of Florida and Caribbean coastal wetlands. Roseate color refers to a Platalea ajaja breast-and-shoulder feather field in late-afternoon light: a saturated, slightly cool deep magenta with the velvet finish of carotenoid-pigmented feather barbs over melanin-substrate flight feathers.

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.
