As a person who changes their hair colour often, I have noticed that each time I change the colour I have a little mini freak-out along the lines of "ohmygodwhathaveIdonenothingIownwillgowiththiscolournoooooooooo!!!"
Usually it works out fine, but there's always that awkward period of re-adjustment while you consider whether it really is ok to still use your favourite purple dress as your lazy-days outfit (still can't decide.. maybe not to work?), or just how comfortable you feel clashing orange or green with purple (completely fine, apparently. How about all at once??!)
I'm not really a big believer in only wearing colours that you deem "suit you" - I honestly think that if you wear something with enough confidence it doesn't matter what colour it is, you will look awesome because you feel awesome.
Dressing for your shape now, thats a different issue entirely..
