Substantial Episcia

#ad1582
Notes

Substantial Episcia (#AD1582) 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 (317°, 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

Substantial
adjective

Latin substantia, substance — adjectival suffix -al, derived from sub-stāre (to stand under). As a color modifier, substantial implies a saturated-and-weighty-and-material quality where the hue carries visual mass and presence. Sits at the bold-and-weighty end of the grid, parallel to weighty and hefty in usage.

Episcia
noun

South American flame violet (Episcia cupreata) — a Gesneriaceae understory perennial native to the Brazilian Atlantic Forest, with deep-magenta tubular flowers above iridescent copper-veined foliage. Episcia color refers to a fully opened Episcia cupreata tubular flower: a saturated, slightly cool deep magenta with the velvet finish of fresh fused-petaled tubular corolla. The genus name comes from the Greek episkios (shaded).

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.
