How to generate a third colour from two layers moving over each other?
I have two layers. One with blue rings and the other layer with yellow rings. When the two layers merge (ie. as a blue ring passes over a yellow ring) I want the result to form a green ring.
So in other words, I’m trying to find a way of creating a third colour (color) from the merging of two other colours.
I’ve tried experimenting with alpha mattes, luma mattes, you name it, but I’m getting confused. Apologies if this is simple.
