Here is an article on opponent process theory, which is actually an idea that comes from psychology (I first learned about it last semester during psychology class). The opponent process theory augments the earlier trichromatic theory (which is that we have cells on our retina that corresponds to the 3 primary lights red green and blue respectively) to explain the sort of afterimage that we saw during lecture by separating colors into pairs that struggle to overcome each other in our vision system.

As the article explains as well, opponent process theory has been generalized to other aspects of human experience, namely emotions, to explain why one might feel especially down after a long happy occasion, and vice versa.

How do we know that these afterimages are evidence for color opponent theory? Couldn't the afterimages just be explained by desensitization of the individual tri-chromatic L, M, and S cones?

@DanCubed The article linked is really interesting! It suggests that emotions are regulated by opposing pairs of primary and secondary processes in the brain. When we experience a primary emotion like fear, a secondary emotion of the opposite type will eventually counteract the initial emotion - bringing us back to our baseline emotional state.
