For the money, these curtains are excellent. I bought the “mineral“ shade, which was described to me as “a dirty ocean blue.“ I find that they take on the color of the surroundings, so mine look more gray green than blue, but the color works beautifully in my bedroom.  My main concern was that they block a sufficient amount of light, and they really do!   I would say 95%. I live in an apartment building with bright lights out in the parking lot, and I am now able to sleep without a problem. And the price cannot be beat!
