Firm Cattleya

#a55bea
Notes

Firm Cattleya (#A55BEA) is a true indigo with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (271°, 77%, 64%) 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 lime. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Firm
adjective

Latin firmus, strong / stable — sharing root with English farm (originally a fixed-yearly-rental). As a color modifier, firm implies a saturated-and-resolute quality where the hue holds its visual position without wavering. Sits at the bold-and-firm end of the grid, parallel to steadfast and unwavering in usage.

Cattleya
noun

South American corsage orchid (Cattleya labiata) — a Brazilian-native epiphytic orchid genus cultivated worldwide for its large frilled-lipped deep-violet flowers, the standard ornamental orchid of mid-20th-century corsage culture. Cattleya color refers to a fully bloomed Cattleya labiata labellum-and-petal: a saturated, slightly cool deep violet with the velvet finish of fresh frilled labellum. Named for William Cattley, an English orchid patron.

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.
