Hi Ludovic,
	The developer who could authoritatively answer your question (Greg  
Couch) is out this week, so I'll take a stab at it:  I don't think  
so. :-)  However, if your goal is to, say, make a movie with a  
background you provide then you could write out image files with a  
transparent background (described in this message: http://www.cgl.ucsf.edu/pipermail/chimera-users/2008-January/002197.html) 
  and use most any image-processing program to compose the Chimera  
images with the background(s) you prefer.
	Despite my flippant answer in the first sentence, I don't really know  
if it is possible to directly change the background.  When Greg gets  
back I hope he will comment on that.  Perhaps you could say more about  
what your ultimate goal is?
