The Trichromatic theory explains how humans perceive color through the operation of three types of cone photoreceptors in the retina, each sensitive to different wavelengths of light corresponding to blue, green, and red. According to this theory, the perception of color arises from the combined activation levels of these three cone types. For instance, if both the red and green cones are stimulated, the brain interprets this combination as yellow.

This theory accounts for the range of colors we can perceive and explains various phenomena related to color vision, such as color mixing and the ability to distinguish between different colors. The basic premise is that all the colors we see can be created by varying the degrees of stimulation of these three cone types. This understanding is foundational to theories of color vision in the field of visual perception.
