The Ontology of Some Afterimages

A good portion of the work in the ontology of color focuses on color properties, trying to figure out how they are related to more straightforwardly physical properties. Another focus is realism: are ordinary material objects such as pumpkins really colored? A third emphasis is the nature of what is referred to by the terms ‘what it’s like’ or ‘phenomenal character’, as applied to color. In contrast, this essay is exclusively about select color tokens. I will be arguing that whether or not ordinary objects such as pumpkins are colored, regardless of what the true theory of color properties is, and independently of any talk of phenomenal character or what-it’s-likeness, some afterimage experiences are very hard to fit into any plausible ontology, physicalist or not.
