Accidental Discovers Can Be the Best
So I was painting my Cadians, doing some practice with colors and painting different features from the norm (flesh, cloth). I had thinned my paint much thinner than usual on accident, but I decided to try it anyways.
I finally, and accidentally, discovered the EXACT thinness needed for paints to make the highlights and colors just really pop and look amazing.
The Emperor granted me a boon.
