I am replacing my vinyl liner and was wondering what color do most people prefer. My old liner was light blue bottom solid white walls and light blue trim around the top. I actually liked the lighter colors because it allowed me to see any algae growth and easily spot leaks. However, it seems as if most liners now are more of the deeper blue color. Any advantage to either one. I know darker colors hides stains better and possibly heat up faster but I would rather be able to easily spot problems with the liner when they occur. Thoughts?
