What effect does using small colored dots in Benday dots technique primarily achieve?

Using small colored dots in the Benday dots technique primarily simulates light and shadow. This method, developed by illustrator Benjamin Day, utilizes varied arrangements and sizes of colored dots to produce an optical blending effect when viewed from a distance. The placement and density of these dots can create the illusion of depth, volume, and dimensionality in an image, mimicking the natural way light interacts with objects and casts shadows.

While this technique can influence color vibrancy and clarity to some extent, the primary goal is to evoke the effects of light and shadow, which enhances the overall visual impact of the artwork by giving it a more dynamic and three-dimensional appearance.
