Out of every 12 men, one has colour deficiency. That deficiency is reduced heavily in women, as they are found once in every 255 woman. Now I’m pretty sure I’m that one guy out of the twelve because after a colour test I got an awful score. As I major in graphic designing, this is pretty depressing. Try it out to see if you’re any better.[Link]
Update: A male friend of mine just had a go at it. His score struck more sorrow to my self being. There is no way on earth I’ll be even close.
