According to the opponent-process theory, the L cones are primarily responsible for detecting red light. When Avalon stares at a light that activates her L cones, she is essentially overstimulating the red-detecting mechanism. Upon looking away, the opponent process kicks in, leading her to see the complementary color to red, which is green. This is due to the way the visual system balances the input from different types of cones to maintain color constancy.
