A color processing device includes the following elements. An image data obtaining unit obtains image data which is obtained by imaging a white member illuminated by a light source and a display device on which a white image is displayed. A color component extracting unit extracts color components of red, green, and blue from image data concerning the white member and image data concerning the white image. A relation determining unit determines a relation between a color temperature and/or a brightness level of the light source and a color temperature and/or a brightness level of the white image, on the basis of a magnitude relation of the extracted color components.
