Coloring the rig controls?

So hey bros, I made these two characters here.

They’re not finished but its still pretty good as a wip I think.
Anyways, my question is if someone knows if its possible to give the rig controllers any different colors, like, the right hand controller to be Red and the left one to be green. I personally love the Pitchipoy Rigger, but I feel that it would be easier to select and identify the controls if you could actually color them

So any ideas?


Use bone groups with each having a custom colour

Thank you so much :smiley:
