@topic question: I say absolutely not! I used to match my fingernail and toenail polish all the time, but these days I find I'm actually preferring doing a really natural looking color on my fingernails, and leaving the really bright and dark colors for my toes. Mostly this is because when I paint my toenails (and especially when I do multiple layers) I find that the color lasts for weeks, so really noticeable colors stay looking nice on my feet.
However, any time I paint my fingernails, I find that the color chips and peels after a couple of days (sometimes faster, but it also depends on the brand a little bit. OPI and Essie tend to be better for lasting longer I find.) So, if I paint my fingernails a really noticeable color, it can start looking kind of crappy pretty fast. That's what I find anyway.
