How do color-changing swim trunks work?

Swimming trunks that change color are not powered by advanced science. There are special microcapsules that are temperature chromic materials. What this means is that if the temperature shifts to a much colder one (Such as jumping into the water or a pool), then the fabric will change its color.

Once the color-changing swim shorts or swim trunks get warm again, then they will revert back to the original color. These swim shorts that change color does not do so because of the water, they change color because of the temperature decrease from the water. That means if the water is warm, such as in a jacuzzi they won’t change color. If you hop out of the ocean in your personal paradise, the swim trunks that change color will do so and revert back to the primary color of the trunks.

What are water-reactive swim trunks?

These water-reactive swim trunks have a muted pattern that can be revealed with contact through the water. These will usually reveal a beautiful pattern to the parts of the swim trunks that are covered in water.
