@adriaannelemans@online.nl : I suggest you make a transparent layer on top of your background layer : to do this, click on a small white page icon with a '+' at the right bottom of the gimp screen. Now you can paint / erase on the new layer without changing the background layer. You can add more transparent layers if you want to use more colors to merge above each other.
