Not the best colour on me and I'm a Winter.
That said. I do think that if you really love something in any colour you should get it and find a way to make it work. You could wear lipstick, nail polish or carry a bag that's your 'spot-on' colour and that would help carry it off. I recently bought a lovely dress in sort of beigey pink colours - totally not me, but I'm planning to make it work with some careful cool red accessorising.
Think of the Hollywood A-listers, I mean - very few of them stick to the same colour palettes all the time. Sometimes the colour that should be all wrong can be made to look very Fashion with the right styling.
