user13962: I'm having some trouble when exporting a sequence in Adobe Premiere CS6. There is a quality loss: image are more pixelated and colors are more bland.
I'm exporting in H.264 format and it's 1920x1080 footage. I tried every possibility of configurations and it keep exporting less good quality.
Here are some screenshots, so you can compare the original quality and what comes out from exportation:


Thank you for your help ! 

user6671: Use a visually lossless (intermediary) codec when going between different editing applications. Avid DNxHR, Apple Prores, Edius HQX, and GoPro Cineform are all examples of intermediary codecs. I personally prefer DNxHR, but all the options I listed are good options.
You can also use dynamic link between After Effects and Premiere, which would be even better.

user13978: Make sure it's not a playback issue. Different players may show differences in gamma etc., you can see it for yourself when opening a h264 encoded clip in QuickTime vs. VLC vs. Flash based player in a Browser. Did you take the Screenshots in the same player when comparing original vs exported material?
