Combined Room Curtain Color Advice?

My living room and dining room are very small. I have cream color carpet throughout both rooms. My question is should I keep the color palette the same in both rooms?

I started with my dining room with black and cream curtains accenting a centerpiece throw rug, etc. in red. I'm thinking of doing the same in the living room but kinda vice versa. Instead of black and white curtains, I could do cream color curtains for a clean look and maybe a black and white area rug (speaking of which can I do an area rug on top of wall to wall carpet?), accented with red pieces i.e. candles, etc.
