 Another important example of an action-based approach to perception is the theory in Noë 2004. Noë defends what he calls the enactive approach to perception. As in the case of Thompson, his theory is guided by Gibson’s work, albeit with modification. Noë sets his view of color within this account, arguing that color is a relational property, involving the object and the environment, and crucially related to perceivers. In his theory of perception, Noë emphasizes the role of perspectival properties. He distinguishes, for example, between size and perspectival size, i.e., size in the visual field or how things look with respect to size from here.
