I got a nice gray carpet. stain proof, 25 year guarantee, the whole 9 yards (stains wipe up like magic). It's from Shaw, the name was silver drop or something similar. Go to the carpet place w/an extra plank of your flooring so you can match it.

Hello. I will agree with you, the gray carpet will not approach, at you in the room and so there is too much gray. Therefore I would choose something like it

I agree with the Nylon cut pile advice. Here's a couple links to great styles we install on a daily basis. Great value but will wear well for many years. Excellent colors with a light tweed of a couple colors to pull in gray but not over commit to all gray! These are the pet protect stain resistant styles, even if you don't have pets, it's just an excellent fiber for stain resistance & cleaning.
