[Chimera-users] coloring of nearly identical protein sequences in multialign viewer

Hi all, I have a clustal aln file or a fasta file with two nearly identical aligned protein sequences. When I view them in the multialign viewer I would like to change the color of the consensus style. That is, residues which are both identical should be just black (rather than red and capitalized) and residues that are not identical should be red (or some other color that contrasts against black). Is there anyway to do this? Better yet would it be possible to not use the consensus at all and color the entire non-matching column a color of my choice? Thanks, Sabuj Pattanayek
