Loading and saving color tables

You can save color tables from optimized images to use with other images and to load color tables created in other applications. Once you load a new color table into an image, the colors in the optimized image are changed to reflect the colors in the new color table.

To save a color table:

1. Select Save Color Table from the Color Table palette menu.
2. Name the color table and choose a location where it will be saved. By default, the color table file is given the extension .act (for Adobe Color Table).

If you want to access the color table when selecting Optimization options for a GIF or PNG image, save the color table in the Presets/Optimized Colors folder inside the Photoshop program folder.

3. Click Save.

Important: When you reload the table, all shifted colors will appear as full swatches and they will be unlocked.

To load a color table:

1. Select Load Color Table from the Color Table palette menu.
2. Navigate to a file containing the color table you want to load--either an Adobe Color Table (.act) file, an Adobe Color Swatch (.aco) file, or a GIF file (to load the file's embedded color table).
3. Click Open.
