Frank Baltic

#1680aa
Notes

Frank Baltic (#1680AA) is a true 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 (197°, 77%, 38%) places it in the highly saturated band at a mid 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 orange. 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.

Baltic
noun

The northern European brackish sea between Scandinavia and the European mainland — the source of Baltic amber and the route of medieval Hanseatic League trade. Baltic color refers to mid-depth Baltic water at the Helsinki archipelago: a saturated, slightly cool deep blue with the optical complexity of low-salinity high-latitude inland sea.

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.
