Frank Marina

#115b67
Notes

Frank Marina (#115B67) is a deep cyan with a jewel character. It carries the deep, saturated richness of a gemstone. Authoritative and slightly formal, it works well for type and heavy UI elements. Its HSL profile (188°, 72%, 24%) places it in the balanced 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 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.

Marina
noun

A small harbor for pleasure boats — the protected water of a yacht basin, a coastal moorage, a riverside dock. The color refers to the calm water of a Mediterranean marina at dusk: a deep, slightly green-shifted blue with the optical depth of sheltered water. Darker than mediterranean, cooler than peacock, with the maritime-leisure association of a word borrowed from Italian into every Romance language.
