I recently had my interior house painted in greige colors,  grays with beige undertones.  I wanted a rug for the dining room which was painted in Sherwin Williams Silvermist, so it takes on a blue, green, or gray tone depending on the light.  This rug looked like it would fit the bill as not being totally gray or totally beige.  Now that I have it, I think I would say it is 75% gray, 25% beige.  It isn't a cool gray in my opinion, and it does go well with the walls, while still blending into the rest of the house which has the more greige colors.  The pattern of white design on the rug is a bit more standoutish than appears in the store photo to me.  There are also subtle changes in the gray color, so that background gray isn't one solid color.     I included a picture of the rug with a small blue rug on it, as well as a beige rug on it.  This can maybe help you see how it compares to those colors.  It does make the rug look gray, but still feel there is a beige undertone to it.
