* Darker colors absorb more light: Darker surfaces absorb a larger portion of the sunlight's energy. This energy is then converted into heat, raising the temperature of the sand.

* Lighter colors reflect more light: Lighter surfaces, like white or light-colored sand, reflect a larger portion of the sunlight. Less energy is absorbed, resulting in less heat.

Think of it this way:

* Black clothing absorbs more heat on a sunny day.

* White clothing reflects more heat and keeps you cooler.

The same principle applies to sand!
