This behaviour is the expected. Color to alpha removes the selected color from all the colors in the image in such a way that when you put the image above a background of that color you will get your original image. To do what you want, and that is to just erase a specific color, you should: 1) add an alpha channel to your layer if it hasn't got any yet (right click on the layer and "add alpha channel") 2) Select -> Select by Color 3) Edit -> Clear _______________________________________________ Gimp-user mailing list [EMAIL PROTECTED] http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-user
