As I'm rebuilding my pool, you can see, without water, how much the liner has faded in 12 seasons.

The floor of the pool is almost white, but where the drop-in steps sit it's much closer to the original color. And, if you can see the patch on the top right of where the steps were, that's the ORIGINAL color of the liner when it was new. I saved the old liner for patches (it only lasted 10 days).
