Aside from the Gundam markers for lining, nothing. I usually keep the default colors of the models, I just like them alot more. The only time I ever painted a model was my 1/100 Infinite Justice, which I colored a dark red (much like what you would see on Saviour). I thought about doing the same when the MG version came out, but 1) I didnt have any paint left at the time and 2) I really dont have a place at my new apartment for me to do it (unlike my old place where I had a garage) 3) I just dont have that kind of time anymore, Im suprised I have time to put them together in the first place.

In anycase, thanks for the compliment
