Tidy Brook

#519b73
Notes

Tidy Brook (#519B73) is a true 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 (148°, 31%, 46%) 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 magenta. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Tidy
adjective

Old English tidig, timely — drifted in modern English to mean neat, orderly. Used as a color modifier for hues that read as composed and unfussy. Tidy beige, tidy gray: moderate saturation combined with optical neatness. Sits at the crisp-bucket alongside plain and modest.

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.
