Fluorescent Clematis
Fluorescent Clematis (#A76CF3) is a true indigo with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (266°, 85%, 69%) 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
Latin fluēre, to flow — adjectival suffix -escent. As a color modifier, fluorescent implies a saturated-and-UV-stimulated-glow quality, the bright color of fluorite-and-ZnS mineral-pigment fluorescent-lamp emission. Sits at the bright-and-cool end of the grid, parallel to phosphorescent and neon in usage.
Asian clematis (Clematis × jackmanii) — a deciduous twining-tendril vine cultivated worldwide as a garden plant, with deep-violet large four-tepalled flowers held above pinnately compound foliage. Clematis color refers to a fully bloomed Clematis × jackmanii tepalled-flower in a Cotswold cottage garden: a saturated, slightly cool deep violet with the velvet finish of fresh broad-tepalled flat-corolla. The genus name comes from the Greek klēmatís (climbing plant).
