FigTree is a graphical viewer of phylogenetic trees and a program for 
producing publication-ready figures written by Andrew Rambaut: 

I added code to Bio::TreeIO::nexus::write_tree (svn 14935) that adds labels 
and colors to the output as comments for FigTree to recognise. This code names 
and colors a cluster in a tree:

my $name = 'ClusterA';
my $color = '#ff0000'; #red
$stem_node->set_tag_value('label', $name);
$stem_node->set_tag_value('color', $color);
foreach my $node  ($stem_node->get_all_Descendents) {
    $node->set_tag_value('color', $color);

Currently these tags are always printed out. If needed, it will be easy to add 
a switch to the nexus module to write them out only on request.
