Neurophenomenological constraints and pushing back the subjectivity barrier

In the first part of this commentary I argue that a neurophenomenological a nalysis of color reveals additional asymmetries that preclude undetectable color transformations, without appealing to weak arguments based on Basic C olor Categories (BCCs); that is, I suggest additional factors that must be included in "an empirically accurate model of color experience," and which break the remaining asymmetries. In the second pari I discuss the "isomorph ism constraint" and die extent to which we may predict the subjective quali ty of experience from its neurological correlates. Protophenomena are discu ssed as a way of capturing in a relational structure all of qualitative exp erience except for the bare fact of subjectivity.
