Blue and Gray Metallic Pigments!
We're thinking about displaying actual powders instead of swatches that we have now. Having them next to each other is a huge help as you can see the tones and shades of each color. Remember, you can always lighten or darken colors if you don't see a shade you want! BTW, you can change the vibrance of a color by adding yellow, orange, red, etc... What other type of floor or countertop can enable you to actually make your own color?
