becvan this made me laugh. I also have auburn hair are consistently get "I thought you had red hair" " I thought you had brown hair" "did you dye your hair?" It depends on the light, what I'm wearing and whether my hair is up or down.

The most ridiculous scenario was when a photocopied (ie black and white) photo of me was circulated before I started a new job, and when I met people every single one said "did you dye your hair?" and I thought what is this, I've never even met these people! Turns out they'd all assumed from the photocopy that my hair was black....
