Dense Cerise

#d21558
Notes

Dense Cerise (#D21558) is a true magenta with a vibrant character. It holds its own as a focal accent, carrying visual weight without tipping into neon territory. Its HSL profile (339°, 82%, 45%) 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

Dense
adjective

Latin dēnsus, thick / crowded — sharing root with English condense. As a color modifier, dense implies a saturated-and-tightly-packed quality where the hue carries maximum pigmentation per visual unit-of-area. Sits at the bold-and-saturated end of the grid, parallel to thick and concentrated in usage.

Cerise
noun

French for cherry — borrowed into English in the late nineteenth century as a fashion term for a saturated red-purple distinct from the orange-shifted cherry red. The color refers to a cerise-dyed Belle Époque silk: a saturated, slightly cool deep red-purple with the satiny finish of dyed silk. Cooler than wine, warmer than fuchsia, with the haute-couture weight of a French color word that retains its specifically Parisian register in English.
