Perfect for my den! Not darkening, but, don't really need that in this room. Want to keep it bright. They are white and a really nice navy. Very crisp look, exactly what I was looking for. They don't look like linen as others have stated. A much flatter weave, (cotton) but are weighted on the corners, have nice tabs on top which give them a tailored look and are consistent on the length. I have paid much more for ready made drapes which varied on length drastically. These are well made and a great value.
