Looking for opinions on waht colors i should use for my tattoo?

Im going to be getting a tattoo on my foot in about 2 weeks of a flower with some sort of swirly design coming off of it. the swirly design wil lbe all black but im having trouble figuring out what color i should use. I know that i def. want pink and light pink in it but i dont want it to be boring, any ideas? Pictures would help too. Thanks
