Has robert pattinson gone red?

Is it just me, or has the stylish Robert Pattinson changed his hair colour?

At the recent premier for Twilight:Eclipse his trademark messed up locks appeared to have a hint of red.

If Robert has dyed his hair and comes clean about it, this could be the beginning of a real boom in colour in men's hairdressing - after all, to paraphrase Desmond Murray, his influnece on men's hair trends is the equivelant of that of Posh on women's.
