Antique Look for my Guest Bedroom

I am planning on redoing my guest bedroom. The room is 11x15 with two windows.

It has beige carpeting. The only furniture in the room is a full antique mahogany spindle bed, a dark oak roll top desk and chair, an antique wicker table and a black toll house lamp.

The windows face North and West.

I want an antique look to the room. The quilt for the bed is light green with a little light blue.

I am unable to decide on a color for the walls. Do I go dark or light? I know I don't want blue but I am thinking a light green (which is my favorite color), beige or gold.

Usually I can pick colors easily but I want the dark furniture to stand out, especially the spindle headboard which came out great after I refinished it.

I plan to put old family photographs on the wall over the bed. I have photos dating back to 1880.

I am also undecided if I should paint the molding. The house is over 100 yrs. old and I think the medium dark molding might look more authentic.

Please give me some ideas.

Thank You, M.J.
