Talk me out of this rug

I am getting a new rug for the great room. I fell in love with this one. I just love it and all the colors work with the colors I have in my room. But I am worried that the black might make the room darker. I need help. I am ordering the runner before I consider ordering the size I want. But I want this rug badly. The picture is an oval but I am getting the rectangle one 7' by 10'/9"
