Pylyshyn's concentration on form perception to demonstrate that early visio
n is cognitively impenetrable neglects that color perception is also part o
f early vision. Thus, the finding of Duncker (1939), Bruner et al. (1951),
and Delk and Fillenbaum (1965) that the expected color of objects affects h
ow they are perceived challenges Pylyshyn's thesis.
