Abstract

Color percept is a subjective experience and, in general, it is impossible for other people to tell someone's color percept. The present study demonstrated that the simple image-classification analysis of brain activity obtained by a functional magnetic resonance imaging (fMRI) techniqueenables to tell which of four colors the subject is looking at. Our results also imply that color information is coded by the responses of hueselective neurons in human brain, not by the combinations of red-green and blue-yellow hue components.
