Dark Seafoam — Dark Seafoam evokes the shifting colors of the sea, giving it its name. It belongs to the Green family: a medium-toned, vivid tone with hex code #1FB57A and RGB values of 31, 181, 122. Its dominant channel values give it a cool undertone that reads as vivid rather than flat. Dark Seafoam pairs well with deep charcoal or black for contrast and works nicely in textile and fashion design. Nearest neighbors: sage.
