Automatic tag/MOC color for graphs

i love the graph so much, it’s seriously life changing and allowing me to see all new things. one question i have – i use #mocs a lot to organize my work. So I have a folder that just includes all names of people, but then MOCs that tell me which chapter they’re in, which system they work in, etc. If I change the color of a file in a graph, I’d like to be able to change the color of all the internal links as well. so if I change the graph color of a MOC called Texas politicians to blue, i’d like all the texas politicians it lists to also change to blue. Is there a way to do that? i’m pretty new here.
