I have a lime green carpet and need to know what colors would go with it because I'm redecorating my room but i can't change the carpet?

I would throw an area rug over the carpet, just to detract from the lime green a bit. Something like this Zebra area rug would look great with lime green and pink, but wouldn't add an additional color to mix things up even more.

You can incorporate the zebra theme in your accessories as well. Zebra lampshades, black and white frames, or a splash of zebra in the form of throw pillows all work together for a great room.
