I am making a wormhole like portal that opens up shrinks and grows for a bit and then dissipates. In the compositor it shows that it is a dark purple color but when I go to render the animation it comes out as black and white and I have no idea what's causing this. I used a youtube tutorial in case you want to comb through it ( https://www.youtube.com/watch?v=TWNLOjw5HYc ) (I know it says its for shockwaves, but I'm using it for my purposes)
as you can see when it renders it loses all color. If you also want to see a picture of my node setup just ask and I'll screenshot it.
