Straightforward Creek

#345c3a
Notes

Straightforward Creek (#345C3A) is a deep green 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 (129°, 28%, 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 violet. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Straightforward
adjective

English compound straight + forward — sharing root with German geradeaus. As a color modifier, straightforward implies a clear-and-direct-and-unencumbered quality where the hue carries the visual register of clear-aim-and-uncomplicated character. Sits at the crisp-and-honest end of the grid, parallel to candid and direct in usage.

Creek
noun

A small flowing waterway — slightly larger than a brook in American usage, slightly smaller in British. Creek color refers to a typical American Appalachian creek in summer: a soft, slightly cool deep blue-green with the optical clarity of slow-flowing forest stream.
