going to store, need help deciding

Jamaicanlove

 I need help deciding.  I want to do double curtains on my windows.  1) The front panels I bought for my living room are two toned: the top is chocolate brown and the bottom is cinnamon. I want to leave the front panels open so light can come in.  What color panels should I put in the back? The walls are a eggshell color. 2) The front panels I bought for my bedroom are also two toned: the top is chocolate brown and the bottom is yellowish gold.  I also want to leave the front panels open so light can come in.  What color panels should I put in the back?  The walls are a khaki/ taupe like color.  TIA
