View and edit colors in a palette

The color table in the Optimize panel displays colors in the current preview when you are working in 8-bit color or less. You can also modify the palette of an image. The color table updates automatically when you are in Preview mode. It appears empty if you are optimizing more than one slice at a time or if you are not working in 8-bit color.

Various small symbols appear on some color swatches, indicating certain characteristics of individual colors, as follows:

Symbol	Meaning
	The color has been edited, affecting only the exported document. Editing a color doesn’t change the color in the source document.
	The color is locked.
	The color is transparent.
	The color is web-safe.
	The color has multiple attributes. In this case, the color is web-safe, is locked, and has been edited.
