Philosophy has dwelt nearly exclusively on differences between ‘good’ and ‘red’ or ‘yellow’. I have long marvelled at this. For there resides in the combined objectivity and anthropocentricity of colour a striking analogy to illuminate not only the externality that human beings attribute to the properties by whose ascription they evaluate things, people, and actions, but also the way in which the quality by which the thing qualifies as good and the desire for the thing are equals—are, ‘made for one another’ so to speak.
There is a longstanding attempt to make dispositional theories of value and of colour run in parallel. But the analogy is none too good, and I doubt that it improves our understanding either of colour or of value.
