Jokes about color blindness

In our feeling, blue and purple are a little close, and green and cyan are relatively close, so we ask the great god not to spit and approach, and then put the blue card, purple card and cyan card together and let him take out the cards that are close to each other. Normal people or people who regard blue imaging as blue will choose blue cards and purple cards, but Mr. Color Blind will choose blue cards and green cards because we use what he sees, his feelings and his natural things, not him.
