HEHEHEHE! yep i know! i was discussing about that with Euro the other day...she also told me than even if SMG has green eyes, seems like they wanted Buffy have blue eyes canon-like...which is of course weird, now add to it her eyes look hazel too! lolz!
oh and dont forget if everything is bathed on moonlight, green also look blueish, that is why Faith brown eyes, look kinda purpleish in my pic
