g am very red green color blind.  Red and green blend together and I can not tell the  difference except at very close distances.   I have this nice yellow Trek  jersey  which I only see yellow, but everyone tell me it is Green.   There are a lot of stories my wife can tell you about my ability to see color.   Yellow is very visible to me, and most of the time so is blue.    back in the mid 50's I attempted to get a pilots license, and  having uncorrected vision of more than 20 -400 and being color blind I was refused.   Don't count on people like me seeing the color green.
