yes, its called red-green.
some people see red as orange, and others like Liz's example.

my friend found out he was colour blind in high school, when he came out dressed in a really badly co-ordinated outfit and his mum asked why he was wearning those colours together, thats when the realised he was seeing different colours to everyone else.

ETA: he knows basic colours, crayola pencil colours. dunno about teal and maroon and those ones!
