You get a final cutscene, which is basically the same no matter what ending you choose. If you have over 4000 (or 5000 depending on a previous conversation) EMS, then the red ending has an extra 5 second scene.
Note, I do not believe red and blue represent renegade and paragon in this case. There are no paragon and renegade choices in the ending, and previous choices don't matter for the most part. The only thing that really matters is EMS.
