Color Blind (True)

When I was at school We had a test to see If I could tell the difference Of colors in front of me. We all stood there in a single line I didn't know what to do The teacher showed us purple I thought it was blue. Then we had another test This time on our own We had to spot a number Within a colored zone. The first was a red seven On a white back ground I thought this test was easy But it got harder as I found. The third page was so different The number I couldn't see For that page was full of dots It completely baffled me. My mate was standing next to me He whispered number three The teacher saw what he was doing And said hey you leave him be. The number there I could not tell The colors blew my mind Then the teacher turned and said Are you color blind. So from that day the colors I see May not be quite true If you see the color purple I will see it blue.
