My brother and I went halvsies on the Clone Wars starter set. He took the Clone Troopers, I took the Clankers. There is just something silly about fielding an entire army of Droids in Star Wars setting that appeals to me.
Color Scheme is similar to what I use on my Eldar:
I use panel accents on the droid units to differentiate them on the table. This way I can have Red B1s, Yellow B1s, Blue B1s, etc..
