Yes it is

So the black liners don’t make the water look black?

With a black liner the water will look turquoise in the sun and be a dark colour on cloudy days.

You will need to be carful with your water chemistry in order to maintain the colour. As you should with any colour liner.

Will a salt water vs chlorine make a difference in water color with a black liner?

No both the same

We put a black liner in and we are still trying to get the water clean there’s a lot of pollen at the bottom so the water is green we bought a vacuum so hopefully that will help
