Perhaps the red could work as an accent wall behind her bed for instance, or on another wall, instead of the whole room.

Then you could indulge her with an accet red wall , which she could redo , down a few years as she grows out of it.

i have no pics of the new room as of yet...we are going to measure and such this weekend. I had considered a neutral color, but see really wants something bright. She had been in an off white room for a year now and has hated every minute of it. so, unfortunaly neutrals are off the table. i have also considered an acid green or a chartruse, since she isnt opposed to green.

i should mention we are on a budget, and since she already has tons of red and black and charcoal items, on the walls just wont work...especailly close to the bed, which has red sheets, black and charcoal comforter set with large white roses on it, and several red and white pillows. the wall color is all we will be able to do, at least for a while

If she likes the red, think it might be a choice for one wall given how dark it is. Some type of a silver even if in a glaze might be a consideration. Red could certainly work with some greens and actually can see black and red more with a green than a blue. Perhaps get some samples of things like the acid green or chartreuse - various green shades and match with various reds to see how they might work together. (Perhaps not the silver - didn't get your last add on message with more details before I posted.) Think an interesting vibrant green might be a choice to consider. Maybe even something like an apple green.

Green could work.

We have a red bedroom accent wall in one of our Model Homes, and it looks lovely. As you can see in the picture it's paired with a neutral taupe, however it would work very well with a light gray. Then use accent peices to make it pop. Picking the right red will be key.

My friend daughter went with the same red and black color scheme. They did white wall with painted bands of red and black with girlie bedding. Looks cute.

I love the idea of an accent wall! Most importantly though, let her express her creativity and vision :D When I was a teen I painted my room a rich purple and loved it for years!

Paint the wall behind the bed a silver metallic finish - adding red or black framed artwork or wall decal will be perfect for that accent wall.
