I've read a few philosophers write that color theorists typically divide into two camps of those who say colors are scientific properties of objects and those who say that color only exists in the mind and are therefor subjective and illusory. These philosophers often offer some alternative to this dichotomy like the idea that colors should be thought of in more relational terms between subject and object. But can't colors be entirely mental or dependent on mental processes but not be illusory?
