Clear Marina

#66c7d5
Notes

Clear Marina (#66C7D5) is a true 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 (188°, 57%, 62%) 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 red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Clear
adjective

From the Latin clarus, bright, distinct — used as a color modifier since the medieval period for hues without haze or mixing. Clear blue sky, clear green water: the implication is moderate saturation combined with optical clarity. Sits at the crisp-bucket center alongside clean and true.

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.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
