Divisionism is a complex system of harmony, an aesthetic rather than a technique.
The point is only a means.
To divide is to seek the power and harmony of color, through representing colored light by pure elements, and through employing the optical mixture of these pure elements, separated and proportioned according to the essential laws of contrast and graduation.
