Bountiful Castor violet
Bountiful Castor violet (#940966) 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 (320°, 89%, 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
Old French bonté, goodness — adjectival suffix -ful. As a color modifier, bountiful implies a saturated-and-generous-and-abundant quality where the hue offers visual richness without measure. Sits at the bold-and-saturated end of the grid, parallel to abundant and plentiful in usage.
Greek Κάστωρ, Gemini-twin-and-horseman. As a color modifier, castor implies a Gemini-twin-and-mortal-brother quality, the visual register of Gemini-Castor-and-Pollux-twin hand-Gemini-twin-and-mortal-brother Gemini-Castor-and-Pollux-twin-and-Argonaut castor-and-Gemini-twin-and-mortal-brother surfaces under Gemini-Castor-and-Pollux-twin-and-Argonaut spring-Gemini-and-Bortle-1-sky stellar-twin-light. Sits at the modifier-and-cosmic end of the grid, parallel to pollux and spica in usage.
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.
