Effervescent Cattleya

#c28ffe
Notes

Effervescent Cattleya (#C28FFE) is a soft indigo with a pastel character. It reads calm and airy, with enough chroma to feel intentional rather than washed out. Its HSL profile (268°, 98%, 78%) places it in the highly saturated band at a light 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

Effervescent
adjective

Latin effervēscēns, boiling-out — present-participle of effervesce, sharing root with fervere (to boil). As a color modifier, effervescent implies a saturated-and-bubbling-and-active quality, the bright color of Champagne-and-Prosecco effervescent-wine carbonation-bubble-light reflection. Sits at the bright-and-effervescent end of the grid, parallel to fizzy and sparkling 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.
