I'm very challenged when it comes to decorating.

Here's the situation. I have a queen bed on a frame but no headboard. I found a nice, inexpensive metal headboard. It is black. I don't have anything black in the room except a couple picture frames, so I'm wondering if introducing yet another color to the room is going to be bad. Here's what I have now:

*beech hardwood floor (with some knots)-- the floor is sort of a rich yellowish amber shade -- light, but not super light;

*bluish-grey walls, very muted and soft;

*medium-dark wood furniture;

*white macrame lace curtains hung on a bronze rod;

*white & grey chenille bedspread;

*there are some gold door hinges that show (gasp! gold! it's that 1970s-1980s gold! I suppose that can be replaced easy enough.)

So now I'm just wondering if introducing black to this mix is going to be too discombobulated. I'm worried about the bronze curtain rod versus the black metal headboard. (I could paint the curtain rod black easily enough.)

I don't want one of those blah looking monotone rooms, but I also don't want a big mishmash where everything is competing against each other. You all always have such good advice. Please help!
