What color paint is on the wall?

It appears that the wood floor is gray and your wall is gray. I cannot see the undertones of those grays but it does appear to me that your carpeting is a darker beige. The left one could be gray but it is hard to tell in a picture. Make sure you are choosing a carpet in the grey family NOT beige. it will never look right. Love the patterns in both carpets.

On the board of small samples, I like the color on the top row 3rd from right. If you want a little darker, the color to the left of that one is also nice.

I like patterned, but in a simple design that's not too trendy.
