The illusion of color

From VAS (271–272):

It’s sort of like whether or not you believe a flower changes color when you put out the lights. If by “color” you mean appearance (an artist’s conception), the answer is yes. If by “color” you mean chlorophyll (a biologist’s understanding), the answer is no.
