The weave is such that the blues appear darker from one side than they do from the other side. Really noticeably. We happen to like this, but it explains some reviewers reporting opposite remarks on the color IRL versus in the pictures. We positioned the rug so that the blue colors are dramatic when you enter the house, but lighter when your seated for maybe watching television or chatting. Wonderful rug. Certainly the largest we've ever had. I feel it is a little thinner than we expected, but a tight weave and good quality.
