Midnight Indygo
Midnight Indygo (#2B2E7F) is a deep blue 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 (238°, 49%, 33%) 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 yellow. For something softer, pull in its analogous neighbors on either side of the wheel.
Etymology
The color of the sky at midnight on a clear, moonless night, far from city lights — almost black, but with a slight blue cast where star-scattered light reaches the eye. The color refers to that exact moment: a very deep, slightly violet-shifted near-black blue with the optical depth of a sky stripped of every direct light source. Deeper than navy, warmer than ink, with the temporal weight of a name that is a precise hour as well as a color.
Polish for indigo (Indigofera tinctoria) — adopted into Polish color terminology during the 18th-century Polish-Lithuanian Commonwealth's textile-trade contact with Ottoman indigo merchants. Indygo color refers to a freshly indygo-dyed Polish-folk linen: a saturated, slightly cool deep blue-violet with the matte finish of multi-bath fermentation indigo on hand-spun linen. Cooler than English indigo and warmer than Russian fioletovyy.
