HAHAH sorry. I was just kidding : ( But I think I am a little colorblind(or colorweak) myself. someone has said it to me, and deviantart was the reason! because I do see a blue background color here, and people do keep telling me that its green o_O
how weird. you haven't problems with only two colors, there's more o_o I have most problems with colors that are really similiar. like bluegreen and greenblue..hahah xD I cant tell that the one of them are more green than blue, or vise versa..and I have a stupid memory when it comes to remembering colors. I can see a yellow car, and I can remember it as green >_>
it has to be weird to those few people in the world who only sees black, grey and white. no colors at all.
It is mainly colors that are close for me as well. Like things that are very clearly red or blue or green or yellow I can often tell, but ones that are more ambiguous I have trouble with. It also depends on what light I am seeing something in at times.
