Hair coloring follows the Law of Color, a system of understanding relationships of color.


The relationships have been tested over and over and have proven to be true. All colors are ultimately created from three pure, or fundamental, pigments: blue, yellow, and red. These three colors can be mixed to create secondary colors, which can then be mixed with the adjacent primary color to create tertiary colors.
