Darned Stream

#3d5d6f
Notes

Darned Stream (#3D5D6F) 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 (202°, 29%, 34%) 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 orange. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Darned
adjective

Old French darner, to mend — past-participle of darn. As a color modifier, darned implies a hushed-and-finely-stitched-and-restored quality, the hushed color of multi-decade Edwardian-period heavily-darned-and-stitched stocking-and-sock textile-finish. Sits at the hushed-and-worn end of the grid, parallel to mended and patched in usage.

Stream
noun

A narrow flowing body of fresh water — smaller than a river, larger than a creek. The color refers to a clear stream over a gravel bed in temperate woodland: a soft, slightly green-shifted blue with the optical clarity of unsilted water. Cooler than aqua, lighter than tide, with the hydrological weight of a word that appears across nearly every English landscape vocabulary.
