Dark brown or regular brown would look Awesome with it!!!!
I think I've seen a bedding(maybe at target?)That was brown with white flowers,it was really pretty and cool! I'm pretty sure it was target so just go on the website,cuz the site has a TON more stuff than the store.

i think tan walls would be nice and red bedding or brown, i prefer red

Depends on your style.
I think you could use a dark red walls and neutral bedding like white or tan. You could do light blue walls and yellow accents and curtains. How about lavender walls and tan bedding? Gold walls and white bedding? Or you could paint the walls a medium brown and do white or tan bedding.... you need to pick the bedding you really like first then pick a secondary color to pain the walls and then pick a third color which is barely in the comforter to use for accessories. Make sure you use bright lighting to keep the headboard from looking dingy. Good luck.

play around with the Sherwin Williams color visualizer to find colors that you like. It is the best paint visualizer on the web, imho. I like how their color palette is laid out, I like that you can search by color family & color name, the "painted" rooms look the most realistic, and it suggests coordinating color schemes. You can literally spend hours:

I think "tuberose" (# 6578) would look good with brown or ivory bedding.

You can also take a photo of your house & upload it to the makeover gallery on this website:

You can get color suggestions & for $5 they'll photoshop them onto your room so that you can get an idea of what it will look like.
