Do you like those general shades ? Becasue they will swing just by walking around the pool. A few hours later there will be new shades. Besides the time of day, there's 100 shades for each type of weather and also the points in the season. Pick something you like in general, without getting too hung up on the details because you'll rarely see it like the pic.
