Colour Matching AE to Hype

Hi All,
very new to this so apologies if I’m making a rookie error! I’m trying to match background colour in a scene to background colour in an AE animation so it looks like the animation is floating in the scene [ colour is #E4F1FE ]. I’ve set the background to the same value but they appear slightly different when i import the rendered video file in Hype. Has anyone come across this before or have any suggestions as to how i can troubleshoot?

cheers,
Ben

Strangely, it seems to work ok in Safari but not Chrome.
