[Poll #1187121]
I'm interested in to see what your guys opinion is because the way I look at it, Lulu's hair is black and nothing more but some morons on cosplay.com thinks it's dark brown: http://www.cosplay.com/showthread.php?t=147188 .The nice easy way for me to remember it is that Lulu is black, Suzaku's hair is brown. Simple, ne? What's your opinion?

Well I just took the RGB values off the official site's artwork. Lelouch's hair breaks down to:

red: 22%
green: 18%
blue: 19%

It leans toward purple-ish more than brown. If it were brown, that green % would be bigger than the blue %. As it is with each value so close to each other, it's more of a slightly reddish dark, dark, gray.
