Frank Cove

#6efbf0
Notes

Frank Cove (#6EFBF0) is a soft cyan with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (175°, 95%, 71%) places it in the highly saturated band at a light lightness. Best used in small doses, like logos, CTAs, focus rings, or highlight text, where its saturation becomes a feature rather than noise. 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

Frank
adjective

From the Old French franc, free, sincere — used as a color modifier since the seventeenth century for hues that read as direct and unhedged. Frank red, frank brown: moderate-to-high saturation combined with optical directness. Sits at the crisp-bucket alongside direct and honest.

Cove
noun

A small coastal indentation sheltered from open ocean — particularly the small coves along the Atlantic coast of Britain, Ireland, and the American Northeast. Cove color refers to a sheltered Cornish cove at high tide: a soft, slightly cool deep blue-green with the optical clarity of sheltered Atlantic water.
