Many color operations do not work on the Indexed images, due to the
limitations induced by the palette.
What you need to do is to transform the image to use the RGB
colorspace. To do this open your image and in the menu use Image ->
Mode -> RGB
Also note that GIF images are indexed by default, so in order to use
color operations with gifs you need to work with a xcf file and then
export the final image.
