[Chimera-users] Chimera - can I tweak the red color on the Red-cyan stereo view

When chimera does red-cyan or green-magenta anaglyph stereo, it limits 
the colors for each eye to one and two of the three colors that are 
emitted by the monitor (red and green/blue or green and red/blue 
respectively).   Changing the red would mean changing the monitor, and 
that is unlikely to help.  It is easier to change the color filters in 
your glasses.  The wikipedia article on anaglyph 3D mentions there are 
higher quality red-cyan glasses that should help -- the section on 
"Compensating focus diopter glasses for red-cyan method" says that 
glasses that are labelled "www.anachrome" are the ones to get.
