Love these blackout shades! They pull up and down easily (and with a hidden plastic pull, which keeps the white fabric clean) and the blackout works very well. I did an outside mount, so some light came through on the side, but it is still a wonderful improvement over the vinyl blinds I had previously.
I purchased the shades with the grey ribbon and I would categorize the grey as having very slightly purple undertones. The white is bright, on the neutral to cool side.
