I was afraid the blue color was going to be too turquoise-y, but it's a very nice neutral blue.  They are definitely not room darkening at all, but I'm actually happy about that.  I was really excited about the back tabs to make it look like the picture with the projecting blue portions, but the tabs don't line up with the blue/neutral stripes on the curtains, so it looks really weird if you just use the back tabs.  I ended up just using the regular rod pocket, and I am still happy with how they look.
