I said NCG is yellow because of the headphones and the trophies. He definitely has some red in there though.

Foa, I would say green.

Shlup, I would say red.

Sharky, I would say green, but there is some blue.

Some are harder than others because I am pretty much 95% green, but most people aren't that much of one color. When my teacher guessed the types of the class, he only got one wrong and he was like 60% red, 40% blue, so people like that are a lot harder to determine.

NOTE: I am going to ask my sales techer tonight what he thinks based on the pictures and see if he gets them right.
