cool toned skin=no red hair?

I think most colour guides are just that, a guide....sure some people wouldnt look as fab as a blonde or redhead but i think the majority of us could pull off alot of colours we should technically stay away from. Both Kate and Kirsten have fairish complexions with blue eyes, are you the same? I think red hair looks good on alot of people, but then again there are many different shades of red, ranging from fire engine red, to more of an orangey red, to auburn red. Im sure you could find a red that would look really good on you =D
The main reason they tell cool skins to stay away from reds is because alot of cool skins have alot of pink in their skin tone and red hair brings out more of the pink tones which can lead to an overly pink looking face.
