I need to adjust the colors in an image. How do I do this with the alpha channel? Thanks
 
Alpha channels have no color. They are grayscale. They are used for making selections. Try loading a selection from the Select menu and choosing that channel as the selection. Then apply color transformations on the composite channels.
