An image processing apparatus has a display to display color images and a storage to store color image data. A first preview controller causes the display to display a color preview image based on stored color image data. A character-area extractor extracts a character area from the stored color image data and a color-designation acceptor accepts a designated color newly set in the extracted character area. A second preview controller changes a color of the extracted character area extracted in the preview image to the accepted designated color, and causes a display of the changed preview image. A decision-instruction acceptor accepts an instruction to set the designated color. A color-change processor responds to the accepted instruction by the decision-instruction acceptor to change information representing a color of the stored color image data to allow the color of the extracted character area to be changed to the accepted designated color.
