Pressing Stola

#510449
Notes

Pressing Stola (#510449) is a deep violet 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 (306°, 91%, 17%) 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 green. 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.

Stola
noun

The Roman matron's long ceremonial robe — particularly the stola worn by Roman empresses and vestal virgins, often dyed in graduated Tyrian purple layers as a marker of social rank. Stola color refers to an imperial Roman Livia-period stola: a saturated, slightly cool deep violet with the matte finish of multi-bath Tyrian shellfish-dye on Roman wool. Distinct from the unmarried-woman tunica and the slave colobium.
