I have a bright kinda dark blue painted room, what color carpet should i have with it?

With dark blue walls, I'd consider a neutral toned carpet. Creams, beiges, or taupes will not conflict with wooden furniture. If anything, they would accent it.

To liven up a neutral carpet, I'd add an area rug that complements your furniture and wall color. With dark blue, you could add a rug like this blue and silver rug, and use the accent colors for your room decor.

What color rug will look good with a dark pink room?

The color of rug you pick depends on whether you want to add a bit of splash to your room or if you just want something to accent the pink.

If you want to add a 'theme' to your room, why not try an animal print rug? A rug like this Animal Print area rug would look great with pink. You can accent with zebra print throw pillows and a few frames or pieces of wall art.

If animal print isn't your thing, you can add an accent rug that would neutralize the dark pink. A rug in cream, white, or taupe would look great with that color. Something like this shag area rug in shades of cream would be comfy on the feet.

There are also other rugs that you can add. If you like girly stuff, this area rug would be great, complete with butterflies and hot pink accents. 

The carpet in my room is forest green. What neutral color best compliments that?
