QOTW 21 : What are your favorite nail polish colors?

Although I haven't painted my nails in months (it's cold and I'm bored too lol), I love it when my nails are painted, they look so pretty! My favorite nail polish colors for the winter are dark purple and navy blue and for the summer it's fuchsia, it looks so good on tanned skin. 

So, what are your favorite nail polish colors? Write specific nail polishes if you want! ;) I'm not at home now, so I can't check out my nail polishes, but I will update this post once I get home. Can't wait to read your answers, spring and summer are getting closer and closer, although it's pretty cold here in Greece.
