Robust Gloom violet

#970662
Notes

Robust Gloom violet (#970662) is a deep magenta 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 (322°, 92%, 31%) 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

Robust
adjective

From the Latin robustus, of oak — implying strength combined with substance. As a color modifier, robust describes saturation combined with body: a robust burgundy, a robust olive. Sits in the bold-and-warm corner alongside strong and solid, with the slightly textural implication of a color that has substance behind the pigment.

Gloom
modifier

Middle English gloumen, to-look-sullen. As a color modifier, gloom implies a sullen-and-darkened-and-overcast quality, the visual register of Northumbrian-moor-and-Scottish-glen-gloom hand-sullen-and-darkened-and-overcast Northumbrian-moor-and-Scottish-glen-and-Yorkshire-dale gloomed-and-darkened-and-overcast surfaces under Northumbrian-moor-and-Scottish-glen overcast-and-low-cloud heather-and-bracken-light. Sits at the modifier-and-mood end of the grid, parallel to murk and drear in usage.

violet
noun

Viola odorata, the European sweet violet — small, fragrant, and the original meaning of the color name in English (the Violet of the rainbow). The color refers to a fresh sweet violet blossom in late winter: a saturated, slightly red-shifted deep blue-purple with the matte finish of small five-petaled flower. Cooler than amethyst, warmer than indigo, with the perfumed weight of a flower used in Roman garlands and Victorian eau de toilette.
