Hmmm...Brown. My colour blindness is very mild, but I have real difficulty telling the difference between Purples and Brown...If I remove brown from the equation I am no longer colour blind and can then move on with my life, get a wife, some kids. Grow a purple tree in the back yard and built a purple treehouse in it. Ahhh yes, t'will be the life. I still remember asking my nursery teacher what colour trees and poo were when I was 3....good times, good times.
