A Light Theory of Color

Traditional theories locate color in primary qualities of objects, indispositional properties of objects, in visual fields, or nowhere. Incontrast, we argue that color is located in properties of light. Morespecifically, light is red iff there is a property P of the lightthat typically interacts with normal human perceivers to give thesensation of red. This is an error theory, because objects and visualfields that appear red are not really red, since they lack theproperties that make light red. We show how this light theory solvesor avoids problems that afflict its competitors.
