I designed a website in illustrator and imported the layers into after effects to animate but the colours are noticeably darker. Footage, Composition, and retaining layer size yield the same results.
Here are some screens:
The first is the design in illustrator
The second is a screenshot after importing into after effects
The blue and image are extremely dark in comparison. I've never had this problem before, any help will be appreciated.
Well, your artwork is in CMYK, which in the context of using it in AE and without color management makes exactly zero sense.
As Mylenium says, albeit rather abruptly, CMYK is not a good working space to be in for web or video. Work in CMYK for print, if you must, but not for anything intended for the screen.
Ah. I did print off this work for my physical portfolio so didn't realise that CMYK was not ideal for after effects as I'm a bit of beginner. Thanks.
