I'm attempting a no purple doors challenge run of the game and I can't seem to figure out paint jumping. I can't find any tutorial resources on it, which makes me think it's just as simple as item jumping, but I can't seem to get even a little bit of height off of it. I'm curious if there's a glitch that prevents collision on the paint can I'm using, but that seems like a stretch. Help!

Paint jumping do not work on the current version of the game, you need to downpatch. This guide should help you: https://www.speedrun.com/talos_principle/guides/kfd62
