The Rock Collection Color Family includes a pale neutral shade of gray, a cool-toned gray with a slightly bluish undertone, a medium to dark shade of gray, and a dark and muted shade of purple-gray. These shades layer together perfectly to create a beautiful deep plum gray. Our ink color families were created to take the guesswork out of layered stamping. The colors in these color families range in shades from light to dark to give superior layering results.
