Modulations

The fact that we do not see black and white as colors is due to the structure of our eyes; they contain cones and a compact net of rods that are responsible for black and white vision. Nevertheless, black and white are classified as independent colors in fashion as well as in arts and design. When a color is mixed with black, white or both at the same time (gray), we obtain so-called modulations. The following illustrations show such modulations:

These modulations are very important, because you can mix any color you like when adding an appropriate quantity of black and/or white to a primary or secondary color.
