I am having a pool built soon. 18x36 with tanning ledge and a couple benches off the tanning ledge. I have a couple liners I’m leaning toward, they are Latham Reef and Latham Terrazzo Caribbean. I have read some things that say it’s best to have a darker back on the liner. I believe the Terrazzo is printed on blue. I believe the Reef is on white. I really like the Reef and the water color but I am fearful of the white back not aging as well. Is this a big deal?
