Yesterday I was driving my husband to work and I mentioned I loved the color of a pickup that went by and he said he didn't like green. It was blue. I said "it was blue" and he asked me if I was sure. Yes, I was sure. So, I know that some men can't tell blue from green, so I did a test on him on blue colored cars and trucks and any blue car that wasn't bright blue he thought was green. Are there women that are color blind or is it only men? I've only read about men. Now I know why when I've asked him to come in my sewing room and help me decide which colors to use for a quilt, he says that they all look good to him. It's because he can't really tell the difference. Poor guy. It must be horrible not to be able to tell the difference in colors. I know he knows red and yellow. It's the blue and green that he can't tell apart. I just have never heard of any women having this disability.
