I am colorblind :( I have trouble seeing red and green.
What caused your color blindness?
I was actually born like this, which is strange because it's less common in females than males. 
ok when was colorblinded first recorded as a problem in history?
I'm actually not sure, but they use what's called an Ishihara color test in order to diagnose colorblindness. I presume most people don't know they are colorblind until much later. Perhaps it was a guy named Ishihara that discovered it?
