ColorGIF is accessed as a Filter. Its dialog box (Figure 14-12) is packed with

features. Like the previous two programs, it offers a preview of the effects of the

settings, although, unlike the others, you can only view one preview at a time.

There is a list of standard Palette options to choose from, and once in a palette,

you can further reduce the bit-depth of the image. It was the first tool to provide

fine-tuning control over the amount of dithering in an image. In addition, there are

white and black threshold settings that can simplify portions of your image and

allow it to be compressed even further.
