Limited Pallettes
Although it is possible to produce a fairly useful range of hues with mixtures of black, white, and the three primary pigment colors-red, yellow, and blue-we find that, owing to the various qualities of the substances we use as pigments, there are many specific color effects that can be obtained only by employing a multiplicity of pigments. Depending on the color key and the tonal harmony of the painting can be obtained by working and mixing a limited number of colors. However, that could be chosen from the variety of each color of the red, blue and yellow, depending on the tonal harmony of the painting as a whole.
