Hey, quick question. I know Jensen's eyes are on the green side of hazel, and when he wears green, it really brings out the green in his eyes. But a couple things I've watched recently, when he wears blue, they almost look a dark blue. Am I nuts? Or do his eyes pick up blue in blue shirts?

This can also be affected by camera filters, esp. if his eyes are hazel. Give a blue cast to the scene (for atmosphere) and hazel eyes would follow suit.

(Matt Smith is similar: hazel eyes that're usually greenish, but certain lights make them look grey-blue.)
