The bottles are painted to help cut down on the algae buildup caused by the light hitting the water in your garden.
A lot of people are concerned about the algae in hydroponic gardens. Even though it's not pretty, algae is your friend. You can't grow with hydroponics and not experience the green slime.
Algae is a sign of healthy water and robust life; not a sign of contamination or problems and only becomes a problem when it grows so thick as to cut off oxygen to the plant beneath. If that happens just rinse with tap water to remove.
