I would rather they didn't match exactly, especially if they are a solid block of color. Since they are two separate rooms, they don't have to be an exact match, but since you probably see them both visually as your eye scans the spaces, then you do need something that will coordinate with the teal.

Or you can go with tan/gold that is in the drapery, if it goes with the wall color in the dining room.

Well on these forums somewhere I've posted photos of my living and dinning rooms. The color in the dinning is pyramid gold and the living is chinese jade. Now the peacock drapes in the dinning have that gold hue in the feathers. My only problem now is to find a valance thaqt goes with mint green and the yellow of the dinning and compliments the teal color of the peacock drapes. I'm just having a brain fart and am confused at what to do, but I need this window treatment done within the next few weeks. Ideas are welcome!
