Help: Color Issue.

I've been working within After Effects with imported illustrator files. The original illustrator character file was not created by me, I've been tasked with taking over development and I can't figure out why the character rig I created in After Effects seems to be changing colour once it's imported into another AE file.

I've verified that everything is RGB and the color profile is 16 bit, but the original file I created the rig in was 8 bit, not sure if maybe that is the issue. I changed it to 16 bit after the fact, so maybe I'm just ignorant to how all of this works. 

I've attached an image of a few of the original rigs, which I can't/don't want to re-use. The one on the right is the one I'm currently working with. I'm at my wit's end and I think I'm at the point where I'm going to try and re-create the rig because I can't figure this out.
