I am a color blind person, usually I cannot distinguish the color of red and green, so every time there is a color blind test, it will be a hard time for me.
But one time, I have a very interesting finding, because the test room for color blind allows two people step in at the same time and using the same test picture, so I have the chance hearing what the person beside me said and just repeat that number to the nurse, and what is more interesting is that, after I knowing what is the number on the picture (I heard for that guy beside me), I actually can "see" that number in that colorful picture, and it's very clear. I think it may because after my brain receives the message from listening, it can affect the result which is send by my eyes. ![6DVO41WF]V9SRD{]JI9FN$B.jpg](http://blog.lib.umn.edu/wlas0006/1001a/6DVO41WF%5DV9SRD%7B%5DJI9FN%24B.jpg)

I specifically remember my BIO teacher in high school giving out these color blind tests. I can recall that every year for the last 10 or so he taught, 4 students on average, found out they were somewhat color blind for the first time knowing it.
