Paul Mitchell® The Color XG® Intensifiers are pure colors that give stylists unlimited formulating options when using Paul Mitchell® The Color XG®. The objective of The Color XG Intensifier shades is to "intensify" formulations by mixing them with other shades, providing great creativity to the colorist. When you mix the intensifiers with other The Color XG® shades, the additional tone/pigment from the shade helps to deliver the balanced and uniform background color, while the Intensifier adds the neutralizing tone or vibrancy tone, depending on the shade selected and desired result.
