Been a while since I was current, but I'm yellow insensitive. Can't pass the color detection charts on a physical if the medical guy checks, but when I got my license, the requirement was being able to distinguish aviation red, green and white from the tower light gun. Red and green are important anymore on runways, blue at night but only on the taxiways. Everything else flashes or is yellow. There may be more but that's what I remember.
Great thing is ground gets written up on my infractions so they are interested in you not screwing up. Up until I became old age, I was so nearsighted I was legally blind uncorrected.
Long story short: I was licensed to fly, bought a taildragger, rebuilt it, flew it, moved on when it got more expensive than owning a house. I knew a guy who was deaf, but a much better pilot that I will ever be, who couldn't land at controlled airports. If you want to do something, accept the challenges you are presented and DO IT.
