Rich Kikyo

#a2178c
Notes

Rich Kikyo (#A2178C) is a true violet 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 (309°, 75%, 36%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. 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

Rich
adjective

Old French riche, wealthy, abundant — applied to color since the medieval period for hues that read as plentiful in pigment. Rich red, rich brown: the implication is depth combined with saturation, a color that gives the eye more to absorb. Sits at the saturated mid-light corner of the engine's grid, slightly warmer than bold and deeper than vivid.

Kikyo
noun

Japanese 桔梗, the balloon flower (Platycodon grandiflorus) — a wild perennial of Japanese mountainsides whose star-shaped corolla unfurls from an inflated bud. The flower is one of the Seven Autumn Flowers of classical waka poetry. Kikyo color refers to a fully unfurled Platycodon grandiflorus corolla: a saturated, slightly cool deep violet with the velvet finish of fresh balloon-flower petals.

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.
