Ah-ha! I retook the test and scores a 4! Interestingly my bad guesses were in a different range this time (?)
My father once bought himself a "brown" suit which turned out to be green. He usually let my mother shop for him. Suspecting that my architect husband was not as color-aware as he thought, I once paired his socks one brown, one olive green, and he wore them that way - all 6 pairs! On the other hand he can take a pen a draw a perfectly straight line free hand.
