 So though o may not itself be F, it can exist in certain conditions, C, such that it has visually relevant similarities to paradigm F things and in that sense it will objectively look F, or look like an F thing—that is, it will itself have a property, a look or an appearance, independently of anyone actually seeing it (see also Martin (2010), Kalderon (2011), Antony (2011), and Genone (2014) on objective looks). If o is then seen in C, o itself will look F to you in perception. Brewer spells this all out in more detail, and with various examples. One is seeing a white piece of chalk as red. The chalk is seen in abnormal illumination conditions such that the white piece of chalk itself looks like a paradigm red piece of chalk—it has “visually relevant similarities with a paradigm piece of chalk, of just that size and shape” (2011: 106). Given that it is seen in those conditions, it looks red to you, even though it is not in fact red. Here, then, we have an account of illusions in which we appeal to objects and the ways those objects are, not the ways they are represented to be, in explaining character.
