Hi Francesco, you can change the background colour in Chimera: Actions->Color->background, then Actions->Color->[choose your colour like you would for colouring atoms etc.]. Then just save your image as usual and it should be on a white background. Also, some of the Publication Options in the Presets menu automatically set the background colour to white. Maybe there is a command line call for changing the background as well? I don't know...

However, on a white background, in order to save ink. Is that a problem of working out the image (I have Gimp only, of which I never gained expertise), or can Chimera provide directly?
