Ok, so im moving into my sister’s old room which has handmade by the Amish (med to light darkness) brown wood bed and dresser. She also has a lime green (but not terribly bright) desk that i would like to keep if possible. I planned on having my room color scheme black and white, and then have bits of color here and there (such as black and white pictures of flowers with a red rose in color). I found a duvet cover i like from pottery barn teen http://www.pbteen.com/products/nouveau-organic-floral-duvet-cover-and-sham/?pkey=cgirls-duvet-covers that i would like to use. I am also planning on painting my back wall behind the bed a color. However im worried that i can’t do this with such a big piece in color in my room (the green desk similar to this http://www.pbteen.com/products/stuff-your-stuff-desk-and-under-desk-cart/?pkey=cdesks) and then i am really really worried about having brown furniture with the black part of my decor…. should i abandon the idea and if so what do you think would be cute… or do you think there is a way i can make it work and if so how? please please please help because i have no idea what to do! thank you sooo much in advance! 
also my mom refuses to let me take out the wood furniture because it was so expensive
It sounds excellent with the black and white wall art with the pop of red, accents in lime and lavender coordinate perfectly….lavender accent wall?
Since black and white is neutral, they compliment wood tones and add balance.

you may want to stay away from the black accessories. go with the rose and keep all of your colors deep and very warm. the lime green desk if possible could be painted the same color red as your rose and that would give you a pop of color but not too much. the dark wood furniture will still look great with the red and maybe find an accent color to add but not black with the furniture.
