Deleting colors from the color table

You can delete selected colors from the color table to decrease the image file size. When you delete a color, areas of the optimized image that previously included that color are rerendered using the closest color remaining in the palette.

When you delete a color, the color table automatically changes to a Custom palette. This is because the Adaptive, Perceptual, and Selective palettes automatically add the deleted color back into the palette when you reoptimize the image--the Custom palette does not change when you reoptimize the image.

To delete selected colors:

1. Select one or more colors in the color table. (See Selecting colors.)
2. Delete the color:
• Click on the Trash button .
• Choose Delete Color from the Color Table palette menu.
