If I preview my project in After Effects all colors appear as they should. However, if I render using either the AE renderer (lossless/best) or Media Encoder (YouTube 1080 H264) the colors are all slightly washed out. I have tested using no color profile and also using sRGB, but the results are exactly the same. My project consist solely of audio and png graphics (it does not contain another video). How can I get the final exported video to have the same colors please?

Update
Hours of reading and experimenting later, I have established that this is not an After Effects problem, because if I open the file in VLC or view it in a browser other than Safari, colors are rendered perfectly. This appears to be a complicated quicktime issue. See here.
I have also tried opening the mov file in handbrake and exporting with the x264 codec - this improved things a bit but not materially enough to matter.
I found so many articles on this, but no definitive answers. There must be video pros out there who know how to fix this - if so, PLEASE help.
