Hi I have a kind of stupid question, but I am wandering if anybody will have an answer. I have a bit of OCD, as we all tend to have traces now and then. Anyway, I came across several pictures of Robert like I have before, being a Zeppelin fan. Nothing really, they were all from different eras: some from the early 70's all the way to current day. But as I was looking I noticed that his eye color sometimes was blue, and then other times it was dark brown. I know that's pretty odd to pick up on, but... It struck me as weird. So I started scanning through other pics, magazines, my Zep DVD's, and found the same results: sometimes his eyes were blue and sometimes brown. Maybe I am crazy, or maybe he is just wearing colored contact lenses sometimes. I tried to blow it off, but the OCD thing kicked in and now for some reason it is bothering the hell out of me. Anyone noticed this, or have an answer?
