Understanding the Indexed Color Mode

The indexed color mode gives you two advantages. You can create images as small as grayscale (8-bit pixels), and you get color instead of shades of gray. Its small file size, and its ability to generate color make is a winning color mode for images displayed on Web pages, as well as graphics used in computer-generated presentations. Its one drawback is the number of colors generated, indexed images generate a maximum of 256 colors (the same as the steps of gray in a grayscale image). The good news is you get to choose the colors. When you convert an image into the indexed color mode, Photoshop creates a color lookup table (CLUT) to store the images color information. When a color in the image cannot be found in the lookup table, Photoshop substitutes the closest available color.
