The Color Table command lets you make changes to the color table of an indexed-color image. These customization features are particularly useful with pseudocolor images— images displaying variations in gray levels with color rather than shades of gray, often used in scientific and medical applications. However, customizing the color table can also produce special effects with indexed-color images that have a limited number of colors.
Note: To shift colors simply in a pseudocolor image, choose Image > Adjust, and use the color adjustment commands in the submenu. For a summary description of these commands, see "Basic steps for correcting images" on page 129.
