View the color table for an optimized slice

The color table for a slice appears in the Color Table panel in the Save For Web & Devices dialog box.

Select a slice that is optimized in GIF or PNG-8 format. The color table for the selected slice appears in the Save

For Web & Devices color table.

If an image has multiple slices, the colors in the color table may vary between slices (you can link the slices first to
prevent this from happening). If you select multiple slices that use different color tables, the color table is empty and
its status bar displays the message “Mixed.”

Customize the color table for GIF and PNG-8 images

You use the color table in the Save For Web & Devices dialog box to customize the colors in optimized GIF and
PNG-8 images. Reducing the number of colors often preserves image quality while reducing the file size of the image.

You can add and delete colors in the color table, shift selected colors to web-safe colors, and lock selected colors to
prevent them from being dropped from the palette.

Sort a color table

Choose a sorting order from the Color Table palette menu:

Unsorted restores the original sorting order.

Sort By Hue sorts by the location of the color on the standard color wheel (expressed as a degree from 0 to 360).
Neutral colors are assigned a hue of 0 and located with the reds.

Sort By Luminance sorts by the lightness or brightness of a color.

Sort By Popularity sorts by the colors’ frequency of occurrence in the image.

Add a new color to the color table

You can add colors that were left out in building the color table. Adding a color to a dynamic table shifts the color in
the palette closest to the new color. Adding a color to a fixed or Custom table adds an additional color to the palette.
