As a process, our Color Palette – ACT Stone brings a triumphant level of sophistication to marble, limestone, travertine, granite and almost any natural stone you may wish. No matter where you intend to use the natural stone we are there to help you through the process. Think of the color palette that is available to you. Beige tones, gray tones, all manner of white color values, basic black, incendiary multi-colors are just a few that spring to mind.
