Why are Swimming Pools Blue?

Swimming pools are blue because of the way light interacts with water. When sunlight hits the water, some of the colors are absorbed and some are reflected. The colors that are absorbed are red, orange, and yellow. The colors that are reflected are blue and green. This is why swimming pools appear blue.

The deeper the water, the more blue it will appear. This is because the longer the light has to travel through the water, the more of the red, orange, and yellow colors are absorbed.

There are some factors that can affect the color of a swimming pool, such as the type of tile or liner that is used, the amount of chlorine in the water, and the amount of dirt or debris in the water. However, the main factor that determines the color of a swimming pool is the way light interacts with water.
