ideas for a very plain teenage girls room

There's pink, and then there's pink. One shade will look fine, another will look like Pepto Bismol or flesh.

That having been said, since it seems you're going to have a lot of black in your room, go with a lighter color. Otherwise, the room will look rather gloomy and it'll feel very dark unless a bright light is on or sunlight is streaming in.

Here's a nice shade:

I have a room that is painted in grey with black accents. I use a very light shade of grey on the walls AND ceiling, then my baseboards and door frames are painted black. You could then add a funky bright color for your own taste and paint your closet doors that color... like a bold bright red or Neon yellow.. yes, I said neon yellow ;-) that color ROCKS when used in small amounts against black/grey. OR if you are a fan of posters, one thing I did for my friends room, I used the exact same color pallatte and on her closet doors I took all of her posters and shaped them so that they would completely cover the doors and look like they were painted on. I used a clear spray paint gloss ( VERY LIGHTLY) and it helped to give the posters a safe covering so they wouldnt tear and wouldnt fall off and they were glossy and looked like they were 'laminated' on the door.
You said something about using pink? Well a good color combination is the black/grey like I was suggesting with pink doors. Use a gloss base grey paint and a gloss base black then get a dull finish pink. All the same, its your room ENJOY and if you dont like it , all you have to do is repaint again. ;-)
good luck with it!

PINK and black.
I am about to re-do my room and here are some ides that I have for me. maybe they will work for you. I am a teen too. Lol.

Well they have this comforter at Target.. I'll try to put a pic on here... Well it is black and white with boldy daisy designs, but it still has an elegant feel to it.. It also brings some pink into the accents with pillows and etc.

What I am planning on doing is getting that comforter and trying to bring some of the pink onto my walls. I have like 4 walls.. all of them are going to be white accept one wall which is a mix b/w pale and hot pink... that will be the accent wall.. it should look really grat.. then I am going to snazz up my desk by adding some more black, white, and pink accents. It should look really good. Well i hope this gives you some ideas.

Oh yeh.. Can you tell me how to put an image on here..
