I recognized everyone but wasn't sure why I recognized the girl and the name of the one in red [though I know why he's read]. After i read through a few posts, I remembered her. If the color's are emotions I Know:
Why Link's green
Why Kenshin's Indigo
The Girl's Purple
Why the dude from berserker's red
Why Gollum's orange
Superman and Vader, wasn't sure. Never watched Star Wars and was just lost as why superman's blue. Thought Courage but that was already taken. Peace is my guess...
