Which color shirt might be best to wear outside on a hot day to stay cool, and why?

White, because it reflects most of the light and does not get hot.

Blue, because it absorbs heat and light.

Red, because it reflects heat and light.

Black, because it absorbs all light and heat.

White would be the best color to wear outside on a hot day to stay cool. This is because white reflects most of the light, including the heat from the sun, rather than absorbing it. By reflecting the light and heat, less energy is absorbed by the shirt, helping to keep the body cooler.
