Curtains are not blackout but more of a room darkening. If there was a special blackout liner sewn in then they could be called blackout. For my purposes, they offer enough darkness. I ordered Ivory. They are more of a putty gray. I'm disappointed in that respect. I wish they were offered in white. Even better would be if they were offered in white with a subdued pattern running thoughout in light gray, beige, navy, etc. to help accent your room. I would also like to see the panels width offered in 60". Curtains are quite pricey on a per panel basis, especially when you factor in the color isn't what was advertised and they aren't truly blackout.
