It's easy enough to produce a quasi-formal schema which, if instantiated, would produce a refutation of Dennett's position:
Denote the color phi experiment by 
; denote
Dennett-targeted traditional theories
of cognition by `TTC.' Dennett's argument, overall, is that
is inconsistent with TTC, and that the only other serious
contender, MDT, should therefore be affirmed. Now, it's known
that in order to show
propositions p and q consistent,
it suffices to find a consistent r which is consistent with p and which
entails q.
Accordingly, our refutation of Dennett will take this form:
We will specify an explanation E of which is such that
;
and 
; and
entails .
