It’s a common misconception that pool water looks blue because it reflects the color of the sky. While the sky is blue, it does not have anything to do with your pool water. Just think about indoor pools that also have the same color as outdoor ones. 

Pool Water

Light Spectrum

Water molecules tend to absorb the colors on the red end of the light spectrum faster. However, the blue end of the spectrum travels faster through the water before it gets absorbed. It is the reason that clean water looks blue. Also, the deeper the water, the bluer it appears because more of the other colors of the spectrum are absorbed. 

Are There Other Colors in Your Pool Water?

In some cases, you will see other colors being reflected in your pool water. Green or brown color in your pool is a sign that you need to hire pool cleaning services. These colors indicate the presence of algae. Moreover, you may also notice other colors because of the paint in your pool or the color of tiles. 

To keep the water sparkling blue, you must maintain the balance of chemicals for your pool. Doing so will inhibit the growth of algae-causing bacteria. However, chlorine does not have anything to do with the color of the water. It is added to pools to keep the water clear, and it is not a dye.
