8. Colorizing maps Most page layout applications allow you to apply a limited degree of coloring to a grayscale image. However, if you require more extensive control over coloring, high-end image-manipulation applications, such as Photoshop, provide the best results. Converting a map image to color mode If you want to colorize your map, you must first convert it to a color mode. Do this by choosing “RGB Color” from the “Mode” menu. Although images must be in CMYK mode for process color separation, use RGB mode while you work in color, even if you intend eventually outputting your map for process color separation – RGB is less demanding on memory than CMYK, thus operations will be faster. You need only change to CMYK mode prior to saving your image for the last time.
