What is the color of the water, and why are swimming pools blue? This is a question you could be asking a million times whenever you are near a swimming pool. You could be wondering why the water is colorless when you put it in the glass, but the water at the swimming pool is blue. Water has molecules that interact with light, giving the swimming pool water a blue color. Light comprises all colors of the rainbow, but the dominant colors are red, blue, and green. However, only the blue color is retained in the water. The deeper the water, the bluer it becomes. There are other reasons swimming pools look blue, so continue reading to understand more.
Reflection of the Light
The blue you see in your swimming pool is obtained from the light. While you may not see the colors of the light, it has all colors of the spectrum, but the most common are red, green, and blue. Water molecules easily absorb the red and green colors in the light, but the blue color takes time, which is why other light colors are not seen. However, if the swimming pool is enclosed, it will take up the lighting color within the room. You may also realize the adults’ swimming pool is dark blue than the children’s swimming pool since the adult’s swimming pool is deeper than the children’s. The interaction between the water and light will determine how blue the pool will be, which is why the pool may not always maintain the same blue color throughout the day.
The Blue Color of the Tiles
Why are swimming pools blue? Another reason is because of the blue tiles. Most swimming pools’ tiles are blue. This makes the swimming pool look bluer. Bluewater signifies cleanness, and that is why people use blue tiles to give the pool water a dark blue color hence attractive. While it feels cool to soak yourself in a blue pool, you wouldn’t love to swim in a green public swimming pool since that shows the water is contaminated by algae or mold, which is unhealthy. If you see other colors reflected in the swimming pool, it means the water contains some impurities, which is why the water molecules are not able to absorb those colors to retain the blue color. This indicates that you must clean your swimming pool to keep it fit. Whether it’s your commercial or home swimming pool, you must ensure they are always clean.
Blue tiles are the most preferable in swimming pools because they give it a clear look so you can see anything inside the pool. This is important even for safety measures since you can easily spot dangerous predators in the water. Even the sides of the swimming pool should have a blue color to ensure the color of the swimming pool is not altered, which can give the wrong impression to the users hence scaring them away. Even though there are even green tiles, many people avoid them, especially in a commercial or public swimming pool, because that will give the pool a green color which is a sign of algae.
Does the Blue Color of the Swimming Pool Come from the Sky?
You might have heard people say that swimming pools are blue because of the color of the sky. But why are swimming pools blue even though they are not outdoors? Sometimes in sunny weather, the color of the sky can be reflected in the swimming pool water turning it blue. But this doesn’t mean that is the reason swimming pools are always blue. The blue color of the swimming pool water is more scientific, which is why even indoor pools are blue, and even outdoor pools will remain blue even when it’s cloudy, and the sky is not blue. Even if it gets cloudy, the water will still retain its blue color because of the ability of water molecules to attract blue color from the light. The blue sky just enhances the blueness of your pool but doesn’t entirely contribute to the blueness of your pool.
Why is it Essential to Have a Blue Swimming Pool?
The blue color shows the natural nature of the pool and water and makes one confident they are in the right place to cool their bodies and minds. This is why many people who know this trick look to make their pools bluer by using blue materials in the walls, floor/tiles, and even the surrounding. When the surrounding is blue, the water in the swimming pool will automatically look blue. Blue pools are associated with purity, which is why hotel owners try all possible ways to manipulate the watercolor in the swimming pools.
Conclusion
Swimming pools are blue because of the interaction between the water and light. Even though there are different colors for swimming pools, blue swimming pools are the most desirable, especially in public pools. People are more likely to relate to the blue color of the water hence the reason many pool owners prefer blue swimming pools.
