Bridled Brook

#365f57
Notes

Bridled Brook (#365F57) is a deep teal 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 (168°, 28%, 29%) 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 red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Bridled
adjective

Old English brigdel, bridle — past-participle of bridle. As a color modifier, bridled implies a hushed-and-restrained-and-controlled quality where the hue carries the visual register of intentionally-controlled-and-restrained color-amplitude limitation. Sits at the hushed-and-restrained end of the grid, parallel to curbed and restrained in usage.

Brook
noun

A small natural stream — smaller than a creek, particularly the spring-fed brooks of New England and northern Britain. Brook color refers to a clear-bottomed mountain brook seen against pebble bed: a soft, slightly cool pale blue-green with the optical clarity of cold spring-fed water.
