Now that UTA already won, I suggest you using the "process of elimination", math. It helps a lot.

I think I have it now. if not then I missed something somewhere.
Also I want to apologize for my misunderstanding, as I misread the rules and did not include repeated colors on purpose.
I'm up for trying again, now that I have a better understanding of the 'hard' rules.
