Agreed. and since windows make an essential and large part of a space, Curtains/ blinds become an important design element.

Either go with a darker shade for your woodwork or a lighter shade for the woodwork than the wall colors. I would use either the same color for all rooms or at least within the same color family. Each room will look different if you paint them all the same anyway due to light, time, of day and your furnishings. I like to choose the very lightest shade on a particular color spectrum. In other word a white with a hint of color. The ceilings do with a soft white or an off white. If you plan to place the TV above the fireplace a darker color will look good as an accent on that wall. If you have a narrow room try a darker color on the smallest wall to balance the size of the room. If your rooms are large try a very dark brown or navy or maroon as an accent wall. Have fun painting. Remember, if you don't like it, it's just paint and paint is cheap.

add some pictures of your space for better suggestions
