Congrats on completing the set. You do have some great patches. It is not easy to find a good one, especially the patch window is that small.
I did complete the set last August. As far as I know, most of the cards can have a patch with 3 or 4 colors. Only two of them have no more than 2 colors and they are Russell Westbrook and J.R. Giddens. I still looking for some with a awesome patch to upgrade my set.
