Gloomy Acai
Gloomy Acai (#46197F) 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 (266°, 67%, 30%) 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
Middle English gloumen, to look glum — adjectival suffix -y. As a color modifier, gloomy implies a deep-and-cool-and-overcast quality, the dark cool-gray of Yorkshire-Moors and Scottish-Highlands late-autumn atmospheric-overcast sky. Sits at the deep-and-cool end of the grid, parallel to sullen and somber.
Brazilian Portuguese for Euterpe oleracea — an Amazon-basin palm whose deep-purple-violet drupe was a quilombola and caboclo dietary staple before its 21st-century superfood commercialization. Acai color refers to a freshly pulped Euterpe oleracea drupe: a saturated, slightly cool deep blue-violet with the matte finish of anthocyanin-rich palm-fruit pulp. The Tupi-derived word entered English via Portuguese in the 1990s.

Accessibility
How this color appears to viewers with the four major color-vision-deficiency types. Computed via the Machado (2009) physiologically-based model. If a tile matches the original, the color reads the same to that viewer.
The color used as foreground text against pure white and pure black, with the contrast ratio and WCAG 2.1 grade. Aim for AA (4.5:1) for body text and AA Large (3:1) for 18 pt+ headlines; AAA (7:1) is the gold standard for long-form reading surfaces.
Wide gamut
The CSS Color 4 wide-gamut form of this color. Both swatches render the same color on every display — the P3 form only diverges from sRGB when a designer pushes channels outside sRGB's reach.
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.
