Shall stalk this thread also, I have been after the perfect pink for years. My Aunty wears a killer lipstick and nail polish for that matter that are the best pink...I shall have to ask her. I've never been able to find the perfect one!!
FWIW I did find what looked perfect at witchery and it was called Fuschia but was all sold out when I got around to going to get some.
Did just google it and there's a pick on a blog of some Australis mineral lipstick in Flamenco for only $12.95 and it looks pretty good.
