I went with Muslin & it was the PERFECT option. I can't think you enough for the spot-on suggestion!

It's not so much the color of carpet as the material and cleaning method you use to keep a carpet looking nice. The easiest cleaning for foot traffic and spills I've found is nylon carpet. I have poly in the bedrooms and nylon in the rest of the house. Nylon cleans better hands down. I just use warm water for spot cleaning. For whole carpet cleaning I just use hot water with vinegar. Soap or detergent attracts dirt having to clean carpets sooner than you have to. Carpet cleaning companies like to use cleaner so they get to come back often. Carpets with a multi thread color berber appears to hide more.

Thank you jck910 and Patricia Colwell Consulting. Both your posts are very helpful. The dining area's floor is the same tile as the kitchen. Only the foyer (small) has hardwood, it was there when we bought the house in 2012, it is blond/yellow. Than you for your advice, I agree that I will need to refinish it and change the color to the color of the new hardwood I choose for the living. I appreciate the emphasis you make on making them both the same color. Thank you jck910 for the idea of using Edgecomb Gray, it looks like a great piece of advice for my space! I really appreciate your help! Thank you!
