True Creek

#42af86
Notes

True Creek (#42AF86) 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 (157°, 45%, 47%) 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

True
adjective

Old English trēowe, faithful — used as a color modifier since the seventeenth century for hues that read as the canonical version of their family. True red, true blue: the saturation is full, the hue is neither shifted nor adulterated. Sits at the center of the bold and crisp buckets, marking the unequivocal middle of any chromatic family.

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.
