This is a nice quality rug with rubber backing. But in addition to the light (nearly light blue) and dark gray tones, there is also a natural color grass woven in. This makes the herringbone pattern more prominent. It also makes the rug appear lighter and it takes on a bluish green tone from a distance. I was going for steel gray so I am a bit disappointed. The tag says the color is Gray Brown. If you want a bluish gray rug, this is for you.
