Lapsing Creek

#63847c
Notes

Lapsing Creek (#63847C) 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 (165°, 14%, 45%) places it in the muted 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 red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Lapsing
adjective

Latin lāpsus, fall — present-participle of lapse. As a color modifier, lapsing implies a hushed-and-slipping-and-receding quality where the hue carries the visual register of gradually-slipping-and-falling-from-attention period-correct color. Sits at the hushed-and-fading end of the grid, parallel to fading and waning 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.
