Imposing Vermiglione

#811a11
Notes

Imposing Vermiglione (#811A11) 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 (5°, 77%, 29%) 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 cyan. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Imposing
adjective

Latin impōnere, to place upon — present-participle of impose. As a color modifier, imposing implies a deep-and-massive-and-architectural quality, the dark cool-gray of Citadel-and-Cathedral monumental architecture against the sky. Sits at the deep-and-architectural end of the grid, parallel to towering and looming in scale.

Vermiglione
noun

The Italian name for vermillion — used in the cinnabar-pigment chapters of Cennino Cennini's Il Libro dell'Arte and across Sienese and Florentine fresco. The color refers to vermiglione in a fifteenth-century altarpiece: a saturated, slightly orange red with the matte finish of egg-tempera-bound pigment. The Italian equivalent of bermellón.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
