Swimming pools that are blue provide a tropical aesthetic and blue pool liners have been popular for decades for that reason. However, pool water with white or liners of other colors also appears blue. There’s a simple explanation rooted in science.
The molecules in pool water absorb light from the red end of the spectrum when touched by sunlight. The light that’s reflected from the bottom of the pool is filtered out by the water and loses much of the red light that was absorbed so it has a blue hue when viewed from above. The richness of the color will vary depending upon the depth of the water in the pool.
At one time, basic blue liners were used to help enhance the crisp, blue aesthetic. It’s a bit of pool psychology that’s highly effective. Today, you have dozens of colors and materials from which to choose that can add new and exciting dimensions to your pool – and the water will still look blue. There are also a myriad of textures that can add extra shimmer to the appearance of your pool.
With the technology available today, you can recreate the colors of locations from around the world. The methods provide a wealth of options for color coordination with your surroundings. The size and depth of the pool and your personal preferences, along with the pool’s positioning in relation to the sun, will have an impact on the color you choose.
There are other colors that you may see in your pool that should be concerning. Brown and green may be an indication that you have algae growth. For those that desire the beautiful blue of a summer oasis, it’s essential that the appropriate chemicals are added, in the right amount, and at the correct time to keep the blue aesthetic alive and well.
