Seafoam Blue — Seafoam Blue evokes the shifting colors of the sea, giving it its name. It belongs to the Green and Cyan family: a medium-toned, moderately saturated tone with hex code #78D1B6 and RGB values of 120, 209, 182. Its dominant channel values give it a cool undertone that reads as moderately saturated rather than flat. Seafoam Blue pairs well with soft pastels for a gentler palette and works nicely in packaging design. Nearest neighbors: sage.
