Final Approach
Years ago, at my first medical, the color vision test was, "Read the row of letters above the green line."I vaguely recall a color blindness exam once which was "go inside and sit in the green chair". Inside there was a muted red chair and a muted green chair where you waited for a could of seconds before someone else did some other exam. I always figured that they must not care much because even if you couldn't tell, you had a 50/50 chances. I think this was inprocessing to the Navy.
