cena .y blue and gray and green furniture are the best for your room. between the chairs the blue one you picked is the best.
the color of your bookcase isn't really good for the room if your desk and bed are the same color you should either change your bedrooms wall colors or you should pick them in lighter colors.light wood colors are excellent for your room.
i think the wall shelve and floor shelves are a great idea. you can decorate it with the stuff you like.
so here are the colors i think you should use: green-blue-gray-light wooden color-white.
but what ever you do don't choose your your surface of the desk as white because i did and i regret it
it does look good but you get really tired by working on it or using your laptop or other stuff
now i barely use it myself. i hope this helped.

olldbobbi Floating shelves are more modern than a bookcase and are really easy to install, and depending on your budget a floating desk will go nicely: [houzz=Floating Shelves 1]

Carolina Photo To Go LLC If you do choose a white desk, you can have a piece of plexiglass cut to fit the top so you don't scratch it or seal it with polyurethane. I think the blue chair and purple wall would look good together. But, if you are only doing purple as an accent wall, I would do antique white on the other walls and put wall art up to brighten it. Gray can get dreary.

Check out Etsy.com for some accessories. Just use their search engine. You can input whatever you like in it such as throw pillows, mirrors. Some people have inspirational sayings on plaques or vinyl peel offs. I like the shop that has a large black initial floating on glass. One shop has a bulletin board in a decorative frame. And I have a high def photography shop, nancyhehmann. Any selection can be customized to your needs with regard to size or if you prefer black or white. The sizes listed are for 8 in x 10 in. You could do 2 or three pics in a similar theme. I think high def photography is very uplifting. You can be any place you want to be in seconds in your mind. Awaken to visions of PEI, Hawaii, Paris, Venice or a cute cuddly llama or striking horse.

Have fun and Happy New Year!

steph1994 i already have the blue chair and the purple wall and the other furniture mentioned except for the white bed. i just want to update it so it looks cleaner and neater with more modernish furniture, thats why i was thinking white and getting rid of the desk and bookshelf and replace it with something smaller and white. but do those colour schemes go? is it yuck to have all white furniture? how do i dress it up? the other walls are a creamy white colour (not crazy about it, but doubt parents will let me paint it)
