okay.. i get to move rooms.. and start over. i know i want white sheets and a black comforter.. but i dont know what color i want the walls.
my new bedroom has no windows.. so i want a bright color..
but i want a lot of my accents to be a deep purple..
so what color goes great with deep purple, black and white?

i think u have named u'r color for the walls... purple. I agree that u should add a hue of the purple. Is u'r comforter going to b strait black or w/ a design? If u have design.. then take that design & transfer it to the walls.. u can do one wall or 2 opposite.

Or if it's going to b plain.. how about doing the walls 2 shades of purple. Something almost rt next 2 ea other in the color palette. THEN... take blue tape.. & level... mark off stripes either vertical or horiztonal.. but not thru the WHOLE wall.. just mayb .. kinda in the middle or above the middle or 15-20" from the ceiling.. then tape off several lines starting where u want the stripes to start.. make one long row of blue tape..( make sure it level) then follow after it down rt next to it... say about 5-6 rows... then take off the ever other row of tape... take u'r roller w/ BLACK.. (yes I said black...) & roll over the tape but not into what u painted. Let dry for a few ( but not totally) then pull tape off slowly. U have black stripes in u'r walls to pull from u'r comforter etc. NOW if u want to add some white... let the black dry throughly... ( 24hrs) then lay tape inbet to make a skinny line... use foam brush & paint there... pull tape.. awsome! ONE more stripe... let dry... if u ran the stripes horiz... go to one or 2 walls... run a blue tape level vertical.. 4 blue tapes.. do it off to the side. like mayb 2-3ft from the corner.. if u chose 2 walls.. do them opposite & opposite corners.. pull every other tape.. then paint those stripes either strait black or strait white or one of ea. pull tape... now u have some design going in u'r room.

Have fun!

I would check into wallpaper or border that brings those colors together.Your white sheets won't be showing. How about some gold in the mix?

Try just using accents of the purple, maybe in even diffrent shades of purple, You could always do a light purple on the walls to make the room look larger and accent with the deep purple and some black that you are wanting. I think that would be nice. You also could always use white crown molding and base boards to help lighten up the room. Good Luck!!!
