Murky Kihachijō

#2c3b55
Notes

Murky Kihachijō (#2C3B55) is a deep azure 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 (218°, 32%, 25%) 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 amber. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Murky
adjective

From Old Norse myrkr, darkness — sharing root with mirkwood. Murky implies low value combined with reduced clarity — the deep brown-greens of pond water, the dim interior of a smoke-blackened bar. Sits at the deep-and-dirtied end of the grid, where the color is both dark and slightly clouded.

Kihachijō
noun

The traditional indigo-dyed silk of Hachijō island in Tokyo's southern archipelago — produced from native kobaicha (yellow-brown) and aogarami (deep blue) dyes since at least the eighteenth century. Kihachijō-iro refers to the saturated medium blue of the silk: a saturated, slightly cool deep blue with the satin finish of plant-dyed island silk.
