I bought the navy blue set for the office/playroom with west-facing windows, which gets killer sunlight in the summertime, even with blinds. I wouldn't call these room-darkening, but they definitely cut down on the brightness and I'm looking forward to seeing how well they do next summer. Since the computer and desk share a small room with the granddaughter's toys and art desk, I didn't want something too formal, nor did I want anything too juvenile.  These are perfect for us, as they are beautifully colored, with a touch of whimsy in the birds. We also love to watch the birds at the feeders outside our kitchen window, so I think my 2-yr-old granddaughter will spot these birds immediately the next time she visits.  I wish they came in valance size, so I could buy them for the kitchen window as well.
