Ah, okay. It is a bed then. It can be converted into terrific seating with cushions, maybe a long bolster against the wall. I like Studio10001's suggestions. Going back to Chookchook's comment up top, I suggest that the first thing you do is find sheets or fabric your daughter would like for her bed and when the two of you have decided on that, post a picture of the fabric here and we can all pitch in with further colour (and other) suggestions. I'm intrigued by what's hanging on the lines strung across the room. ?

I like the idea of bringing some black into your room. I think lamps with black shades would look very nice and because you love pink you could get black chairs with pink cushions. You need to tie in the pink in other areas of your livingroom but I would not overdue it. It's a beautiful shade of pink but too much of it would be too overpowering in my opinion. Post some more pictures of your room if you can.

There are so many wall colours that would work with your neutral furniture, that the first thing to do would be to consider what colours you might want to use in the rooms. Look for inspiration pictures and create an idea book, then use what you like to help you choose rugs, drapes and bedding before choosing the paint colour. Do you have any existing art that you want to use? That could give you clues for fabric colours and style. I wouldn't use the same colour scheme for the two bedrooms, exactly, although I might try to make them look similar by using some colours in common and keeping them in the same style. On the other hand, if you have a child who has strong ideas I'd say let him or her have considerable say in the matter for that bedroom (just this side of reason).

I like the 4th one the most, however it is very difficult to see the shades as they really do not show up in your photos. Look at lamps Plus.com 'sale' . be sure to get ones that are between 26 & 30" tall. Your side tables can be different, in fact should be, but the lamps should reach close to the same height. No more grey please.
