Hey peeps,
we're currently working on our submission and thought about post processing.
Is post processing allowed? because its technically not 2 colors?
Thought id ask so were not breaking any rules :D

They've said in other posts that the color output needs to be in two colors (color output meaning what the user sees on screen)

It depends on the post processing. If the resultant pixels that the user sees on the screen are not one of two colors, it will likely suffer in the "bitness" rating. If the post-processing is to filter everything down to exactly two colors, then that might be the type of processing you'd want to use.
