Color Schemes

So the other day i was using the Space Marine Painter on Bolter and Chainsword  (Link) and i came up with a couple of color schemes for marines from different chapters in my Renegade army (name to be determined)

Now on to pictures of them;

Crimson Fist Sergeant

Blood Raven Librarian/Sorcerer (all depends on the codex i use)

Former Soul Drinkers Assault Company Captain

Let me know your opinions or  suggestions for more color schemes, since all of the space marines are going to be from different chapters or legions, so i will need to have ideas for more color schemes
