Firm Gloom violet

#a10567
Notes

Firm Gloom violet (#A10567) 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°, 94%, 33%) 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

Firm
adjective

Latin firmus, strong / stable — sharing root with English farm (originally a fixed-yearly-rental). As a color modifier, firm implies a saturated-and-resolute quality where the hue holds its visual position without wavering. Sits at the bold-and-firm end of the grid, parallel to steadfast and unwavering in usage.

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.
