4 by 6 is stronger darker pattern than runners. I purchased 4 runners.  Fair quality for price not as nice quality as some rugs but get what you pay for. Pretty good in person good for the kitchen.  Not machine washable and need rug pad. Looked at so many rugs needed one that tied in orange walls with green flooring. The coral and pink and green grey look great together.  I actually prefer the less strong pattern and colors of the runners.  Colors tie well together.
