Rigging can be an interesting art form. For the most part, the audience will never see your work.
The only ones using your products will be the animation team and the lighting team. That being said this does not mean they can't look great.
Lately, I've found that making nice shapes and making the rig look nice is actually one of my favorite parts of the process. Enjoy this video where I show how I add control custom control colors.
