Edit Palette

	Click on the Image menu, then click Edit Palette. A dialog will appear showing all the colors at use in the image. This group of colors is the palette. For images with 256 or fewer colors. If your image has more than 256, you can use the Decrease Color Depth option on the Image menu to adjust it. Click on any color and information about it will be displayed below. The index is where the color appears in the palette for that image. Its value is the set of RGB numbers that make up that color. Double click the color to bring up another dialog for editing the color. Your changes will appear in the image as you make them. Click refresh to update the palette display. When you are satisfied with your changes, or to exit without making any changes, click OK to close the dialog. This has much the effect of a paint program's fill tool, dumping a new color into a selected area. Here, though, the color will change wherever it is in the image. Dark gray highlights, for example can be made a lighter gray. This action can be reversed by the Edit menu's Undo command.
