Firm Sway Violet

#9c0651
Notes

Firm Sway Violet (#9C0651) 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 (330°, 93%, 32%) 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

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.

Sway
modifier

Middle English swēven, to-move-side-to-side. As a color modifier, sway implies a side-to-side-and-rocking-and-rhythmic quality, the visual register of willow-branch-and-tall-grass-sway hand-side-to-side-and-rocking-and-rhythmic willow-branch-and-tall-grass-and-pendulum-clock swayed-and-side-to-side-and-rocking-and-rhythmic surfaces under willow-branch-and-tall-grass-and-pendulum-clock breeze-rocked-and-pendulum-and-cradle riverbank-meadow-light. Sits at the modifier-and-mood end of the grid, parallel to drift and float 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.
