Murky Anchor

#3f338e
Notes

Murky Anchor (#3F338E) is a true 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 (248°, 47%, 38%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. 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

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.

Anchor
noun

The maritime and military attribute — the metal hook that holds a vessel to the bottom — and the deep blue color named after the dark wool dyed for British and American naval anchor crews. The color refers to an anchor-blue dyed wool: a saturated, slightly muted deep blue with the matte finish of heavyweight wool. Cooler than navy, warmer than midnight, with the maritime weight of a working-blue distinct from the dress-blue of officer ranks.
