Here is an interesting fact. During World War II (or maybe I, I can never remember :oops: ) they would send soldiers who were color blind up in balloons or post them on a high ridge because they could see where the enemy had trenches and dug in. It's because they weren't fooled by the camouflage but could see where the enemy was by the different hues in the surroundings.
