The bg="white" is redundant if color=FALSE. 

Incidentally, if color=TRUE, setting bg="white" is IMO bad practice 
(although it seemed like a good idea at the time), since it creates 
settings with a white background while the other colors are only 
suitable for a dark background. To make it more difficult for users to 
achieve this, the 'bg' argument has been dropped from trellis.device in
