I gave this a low rating for three reasons: 
1) the color is much darker (more of a tan) than I was expecting.  
2) I ordered 6 panels, and 5 of them are one color, but the 6th one has a green hue when the light shines in.  I've thought about returning it, but I'm worried I'll just end up with another color.
3) They have a nice white flanel backing, but in the cream color they are not al all darkening.
