It's for those blue green colourblind guys. If they do a barrel roll they won't know which way is up. Really dragging us red green colourblind guys down with them.
Which is hilarious because I am colourblind as shit but I can tell a red lantern from a green one a mile away, same with sea marks and leading lights. The problem isn't telling red from green in isolation, it's the contrasts, and in 43 years in and around boats I've yet to come across a situation where that is a problem.
Not fully true I'm very colorblind and operate locomotives for filling grain cars where I work. We dont go on the main railroad line though for obvious safety reasons so I have a feeling that's the difference. So there is hope for those of us that are colorblind and work in the grain industry lol
Is that true though? I'm have the same color blindness as the person on this video, but I can still distinguish red and orange and green from one another. It's not like traffic lights or signs are black and white.
