White pond liner?

What is the advantage or disadvantage of a white versus a black pond liner?
I am considering using one or the other for 2 foot deep fish pond, water feature etc.

Answer:

Use black 40 mil butyl rubber pond liner. White attracts algae, black does not. Black liner disappears. White just get dirty.
Black looks natural. White does not.

I can't even find any white pond liner for sale online and have never seen it used.
