Adamant Diana violet

#9d1866
Notes

Adamant Diana violet (#9D1866) is a true 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 (325°, 73%, 35%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. 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

Adamant
adjective

Greek adámas, unconquerable — derived from a- (not) plus damnan (to subdue). As a color modifier, adamant implies a saturated-and-rock-hard quality where the hue maintains diamond-hard pigmentation. Sits at the bold-and-resilient end of the grid, parallel to indomitable and ironclad in usage.

Diana
modifier

Latin Diana, Roman-goddess-of-moon-and-hunt. As a color modifier, diana implies a Roman-goddess-and-moon-and-hunter-and-virgin quality, the visual register of Roman-Diana-and-Ephesian-Artemis hand-Roman-goddess-and-moon-and-hunter-and-virgin Roman-Diana-and-Ephesian-Artemis-and-Lake-Nemi diana-and-Roman-goddess-and-moon-and-hunter surfaces under Roman-Diana-and-Ephesian-Artemis-and-Lake-Nemi Aventine-Hill-and-Nemi-grove moonlit-grove-light. Sits at the modifier-and-myth end of the grid, parallel to luna and hera 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.
