The apparatus includes a microprocessor, a ROM with a stored program, a RAM with midifiable color data a CRT display for displaying color images, and a keyboard with a cursor-positioning key for identifying a pixel of a displayed color image, and a color menu and H (hue), L (lightness), S (saturation) color modification keys. In response to actuation of one or more of the color modification keys, the microprocessor, under control of the stored program, modifies the stored color data, and uses the modified color data to control the color guns (red, green, blue) of the CRT to modify the color of the identified pixel. | |
