Limitation of Trichromatic Theory in Color Perception

Very Hard Unit 3: Sensation & Perception Visual System

In the context of the visual system, various theories explain how we perceive color. Among these theories are the trichromatic theory and the opponent-process theory. Trichromatic theory posits that the human eye contains three types of cones sensitive to specific wavelengths of light, while opponent-process theory suggests that visual information is processed in pairs of opposing colors. Considering the mechanisms of color vision and how these theories help to explain it, which of the following statements best describes a limitation of the trichromatic theory when accounting for color vision?

Trichromatic theory cannot explain the phenomenon of color afterimages.

Trichromatic theory does not account for the perception of brightness.

Trichromatic theory is limited to the perception of primary colors only.

Trichromatic theory fails to explain the color constancy effect.

Trichromatic theory accurately accounts for all aspects of color vision.
