Why are summer clothes usually made of light-colored materials?

- Reflection: Light colors reflect more sunlight, while darker colors absorb sunlight. This means that wearing lighter-colored clothing helps keep the body cooler in the summer by reducing the amount of heat absorbed from the sun.

- Evaporation: Lighter-colored fabrics also tend to be lighter and more breathable, allowing sweat to evaporate more easily, which further helps in cooling the body.

- Psychological effect: Psychologically, lighter colors are associated with coolness and freshness, making them more comfortable to wear in warm weather.
