What color is concrete? Thanks to Arto’s Chameleon Express color automation system by Davis Colors, Arto can make thousands of colors on demand. The Chameleon system is much like the paint tinting systems you see in paint stores, but is designed for concrete manufacturers. The Chameleon system blends liquid red, yellow and black iron oxide pigments together in accurate ratios to achieve a wide range of colors.
The synthetic pigment is non-toxic and made from 60% post-industrial scrap steel and iron. One source of scrap steel is from car manufactures. Once the car parts are stamped and cut the remaining scraps are used by pigment manufacturers to make iron oxide pigments. Iron oxide pigments are used in concrete because they don’t fade. The active ingredient is pure inorganic pigment which is made in a process of oxidizing metal, in essence, “fading” metal into a pigment. The resulting pigment concentrate is impossible to fade. That’s why it’s the same active ingredient in another permanent coloring application: Tattoos. Concrete, on the other hand does change with time and weather exposure. You can keep concrete looking fresh by protecting it with periodic applications of a high quality sealer.
