“Maund has also extended his argument particularly with reference of color. Color he sees as a dispositional property, not an objective one, an approach which allows for the facts of difference between person and person, and also leaves aside the claim that external objects are colored. Colors are therefore “virtual properties,” in that it is as if things possessed them; although the naïve view attributes them to objects, they are intrinsic, non-relational inner experiences.” source:wikipedia
