You must have all the correct pigments or blends and  the formulas to use these swatches for color matching  , They have color numbers on the back and can be used to order colors or with our color mixing system. These swatches are custom made and non returnable.  

Take the color swatch that matches closest to the material that will be colored, back side will have a color code.  When you have the code, you will find that code inside the formulation book which will have a break down for mixing that color using the formulation pigments .
