Heritage Brook

#365a52
Notes

Heritage Brook (#365A52) 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 (167°, 25%, 28%) 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

Latin hereditas, inheritance — used as a color modifier since the late twentieth century for hues that read as drawn from historical palettes. Heritage green, heritage red: moderate-to-low saturation combined with the optical impression of paint formulated to match a specific historical period. Sits at the hushed-bucket alongside antique.

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.
