"...they told me of color, that it was an illusion of the eye, an event in the perceiver's mind, not in the object; they told me that color had no reality; indeed, they told me that color did not inhere in a physical body any more than pain was in a needle. And then they imprisoned me in darkness; and though there was no color there, I still was black, and they still were white; and for that, they bound and gagged me."
