| You can try to brush off any discoloration with a soft nylon brush and vinyl liner cleaning liquid available at pool supply stores. In all likelihood the sun has faded your colors and only a new liner will brighten up your pool.
New liners can have a pro-rated warranty for up to 30 years now, but they do not guarantee against color loss/fading. Pool chemistry plays heavily on how long your liner will hold its color and ultimately last until needing replacement. This is one of the reasons that proper water chemistry maintenance is so important.
I hope this information is helpful.
