  The description of the anti-representationalist scenario is typically completed with the following three features. First, Invert is able to use her color vision to reidentify objects, distinguish objects from their backgrounds, etc., with more-or-less the facility of Nonvert. In Locke’s phrase, Invert “would be able as regularly to distinguish Things for [her] Use by those Appearances”. Second, Invert has been spectrally inverted from birth (or at least for a long period of time). Third, Nonvert and Invert belong to the same linguistic community: in particular, they use color vocabulary in the same way, applying ‘red’ to tomatoes, ‘yellow’ to bananas, and so forth.
