Lambent Vermillion
Lambent Vermillion (#EC6CB2) is a true magenta 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 (327°, 77%, 67%) 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 teal. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Latin lambēns, licking-lightly — present-participle of lambere (to lick). As a color modifier, lambent implies a saturated-and-soft-flickering quality, the bright color of candle-flame-and-firefly gentle-flickering light-emission against the surrounding darkness. Sits at the bright-and-soft end of the grid, parallel to glimmering and flickering in usage.
From the medieval Latin vermiculus, little worm — originally the kermes insect again, before the name transferred to ground cinnabar (mercury sulfide) when that pigment displaced kermes for warm reds. The color of Roman frescoes, Chinese imperial seals, the lacquered shrines of Kyoto. Brighter than crimson, hotter than scarlet, with the slight orange edge characteristic of the mineral source.
