Smothering Amethyst
Smothering Amethyst (#20093B) is a deep indigo 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 (268°, 74%, 13%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. For a confident two-color system, pair it with its complementary lime. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
Old English smorian, to suffocate — present-participle of smother. As a color modifier, smothering implies a deep-and-overwhelming-and-pressing quality where the hue is dominated by an enveloping darkness. Sits at the deep-and-overwhelming end of the grid, parallel to suffocating with kinetic register.
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.
