Murky Edo

#1e2a80
Notes

Murky Edo (#1E2A80) is a deep blue 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 (233°, 62%, 31%) 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.

Edo
noun

The Tokugawa shogunate's capital (1603–1867), now Tokyo — and the period when aizome indigo dyeing democratized to commoners under sumptuary laws restricting brighter colors to the daimyo class. Edo color refers to an Edo-komon indigo-dyed cotton: a saturated, slightly cool deep blue-violet with the matte finish of fermentation-vat aizome dye on commoner cotton.

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.
