They dilute colors to use different colors. This is done in three ways with different results: A- using white color according to a clear degree or satiety of the requested color to white. White mixing reduces the intensity of the original color to some extent and makes it cooler, for example: red liver in mixing with white blue tali. Dark purple has an offensive state, but if white is diluted, it becomes a calm, vibrant, vibrant color. (b) with grey color: In this case, the color becomes less sharp, and it becomes less dark. With the use and mixing of supplemental colors, colors can be dilute by mixing their own supplemental colors and, for example: in yellow and purple mixing, intermediate colours between dark and purple dark yellow produce green and red grey and black. At the same time, it should be noted that if mixing the first three colors (blue-red) will be the result of the diluted and dark color and, according to the mixing, the voxter would wish to be yellow or red or black.
