Luminous Hutt

#e74eb4
Notes

Luminous Hutt (#E74EB4) is a true magenta with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (320°, 76%, 61%) 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

Luminous
adjective

Latin lūminōsus, full of light — adjectival suffix -ous, derived from lūmen (light). As a color modifier, luminous implies a saturated-and-light-emitting quality where the hue carries internal-glow visual register. Sits at the bright-and-saturated end of the grid, parallel to radiant and resplendent in usage.

Hutt
noun

Australian Hutt Lagoon near Port Gregory (Western Australia) — a hyper-saline coastal lagoon whose deep-magenta water is colored by Dunaliella salina halophilic algae cultivated for β-carotene extraction. Hutt color refers to a Hutt Lagoon surface in midday sun: a saturated, slightly cool deep magenta with the matte finish of halophilic-algae-tinted hyper-saline water under high-altitude clear sky.

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.
