Dim Amethyst

#420343
Notes

Dim Amethyst (#420343) is a deep violet 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 (299°, 91%, 14%) 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

Dim
adjective

Old English dim, dark, obscured. As a color modifier, dim implies reduced luminance without specific saturation effect — a dim red is a less luminous version of red rather than a less saturated one. Sits at the value-only end of the deep grid, closer to dark than to plush.

Amethyst
noun

A purple variety of quartz, colored by iron impurities and irradiation — the gem of February birthdays, the bishop's ring stone, the bowl of Roman wine cups (the Greeks believed it prevented drunkenness, and the name amethystos means not drunk). The color refers to a polished amethyst cabochon: a saturated, slightly red-shifted deep purple with the gem's signature internal life. Cooler than orchid, deeper than lilac.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
