Slate Grey is the perfect blend of two contrasting colors. Most houses are either brown tones or grey tones. Slate grey blurs the lines between the two making it a very unique flooring material. The stone puts off a primarily grey tone when sitting by itself, but paired with brown secondary colors this stone blends beautifully with any setting. That makes this stone not only beautiful but also versatile to go along with a plethora of color choices. This product is sold per square foot.
