Pressing Pourpre

#6c0012
Notes

Pressing Pourpre (#6C0012) is a deep red with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (350°, 100%, 21%) places it in the highly saturated band at a dark 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

Pressing
adjective

Latin pressāre, to press repeatedly — present-participle of press. As a color modifier, pressing implies a deep-and-imposing-and-weighty quality where the hue exerts visual force on its substrate. Sits at the deep-and-weighty end of the grid, parallel to crushing with insistent register.

Pourpre
noun

French for purple in its classical sense — the deep red-purple of Tyrian dye and the pourpre cardinalice of medieval French ecclesiastical dress. The color refers to a pourpre-dyed French silk: a saturated, slightly cool deep red-purple with the satin finish of plant-and-shell dye. The French cousin of porpora.
