Color theory should be useful! I found early on in my career that I was going to need to have a strategy for developing a coherent color scheme in a picture rather than trying to just guess what would look best. This is the logic of why I choose what I choose in every single picture I paint and how to get to that color. This is not a how to mix paint video series. It is the explanation of how I know what paint to mix in order to get to the desired outcome.
