Make the good guys lighter colors, closer to white while the bad guys use darker colors, colors that are closer to black
Different shapes, if you examine any disney movie you will notice the heroes are always made up of round lines where the bad guys are very sharp angles and straight lines.
The other thing you can also use is lines, having the good ships feature more horizontal but have the evil ships feature more vertical features
USE AFFINITY (similiarity)
This corresponds to Contrast, when you choose what materials and colors define each side, make sure everything that happens with them are similiar.
By doing this you will really allow the users to feel the difference between the two sides. Think about Star Wars, you know who is on the light side and the dark side right away. This is done through contrast and affinity. If you want the player to really feel like they made a choice use them.
I'm a filmmaker but I love creating in little big planet, I'm working right now on building up my creating skills first, none of my levels are that cinematic. Once I feel like I can get gameplay down though I hope to do a more story driven level like what you are trying to accomplish.
Good luck and I can't wait to see the final product.
