Bleak Gentian

#233c3b
Notes

Bleak Gentian (#233C3B) is a deep cyan with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (178°, 26%, 19%) places it in the muted 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 red. For something softer, pull in its analogous neighbors on either side of the wheel.

As a color modifier, bleak implies a deep-and-cold-and-comfortless quality, the dark gray-pale of Yorkshire-Moors and Hebrides late-winter atmospheric-light. Sits at the deep-and-cool end of the grid, parallel to grim and bitter in atmospheric register.

Gentian
noun
