Not only the colours, but that symbol on his chest seems to have been borrowed from the good Doctor's wardrobe. How strange.Heh.
I can't help but think about the recent BBC/BBC America Robin Hood show's Sheriff. Who is bald, and hilariously awesome and gloriously evil.To me now, there is no other Sherff, even if they dress like Doctor Strange.
As a lifelong resident of Nottingham (as in Sheriff of ...) I must point out that the position of Sheriff of Nottingham has existed since the 7th or 8th century. Therefore Doctor Strange is stealing the Sheriff's colours & costume.
Convincing argument Chris, but hardly definitive. Ol' Doc Strange has traveled back in time at least as far as the era of the Pharoahs.
