Thanks for your reply.
Addtional information:
Im using Premiere Pro CS6
I shot the film with my Canon 600D so that would be .MOV files but I was exporting the movie in H.264.
Im editind this short film in PC and there this problem happens. When I play the video in my 27" iMac the colors look great.
My project sequence is correct. Full HD 25 fps. I used the DSLR preset in premiere.
I would upload a screenshot but I am not in my computer right now so I will do that soon.
