The color in the photo simply does not do this pillow justice. It's actually a vibrant shade of chartreuse, though not too bright and overpowering.
While everything about this pillow is excellent, I'm not sure I can say that I would have purchased this had I seen it in person first.
The fabric is a rather coarse and loose-woven linen that's reminiscent of burlap. Not the most refined or comfortable throw pillow, but it still looks nice. And for the price, it really can't be beat.
