Cool Whippet

#687d7c
Notes

Cool Whippet (#687D7C) is a true cyan 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 (177°, 9%, 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

Cool
adjective

Whippet
noun

English sighthound breed — a mid-sized cousin of the greyhound developed in the late-19th-century for coursing and racing. Whippet color refers to a brindle-gray Whippet dorsal-coat in raking sun: a balanced cool gray with the matte finish of melanin-and-pheomelanin-banded short-coat fur with the characteristic brindle tiger-stripe pattern.
