Why my whites tu purple on after effect
Hello, I wanted to replace a video rush from premiere pro with an after effect composition and it turns out that when it opens in After Effect the image darkens and my whites seem to turn purple.


The rush then becomes the same in Premiere Pro.
I tested several active colorimetric spaces but none gives me the rendering that I have in Premiere Pro. (Also how do I know what my color space is in Premiere Pro?)
Sorry for my poor English.
Thank you in advance for your answers.
