 There is a group of views about color, which come under one or all of the labels, Color Irrealism, Color Eliminativism, Color Fictionalism. These titles are a little misleading, since some theorists also talk of there being colors in the sense of being dispositions to cause experiences of a characteristic type, and/or being (attributes in/of) sensations. Following our earlier discussion, in  section 1.2,  we may take it that what the color-Eliminativist is denying is that material objects and lights have colors of a certain kind: colors that we ordinarily and unreflectingly take the bodies to have. That is to say, these views are usually committed to an “Error theory” of visual color experience. Indeed the theories are often referred to as “Error theories” of color. Prominent contemporary defenders of variants of this view are Hardin (1988), Boghossian &amp; Velleman (1989), Averill (2005), and Maund (1995, 2006, 2011). Earlier defenders were Galileo, Descartes, Locke and others.
