Is it true that the sand is the same color as the sky?

Yes, the sand is the same color as the sky. Sand is a type of sedimentary rock composed of particles of various sizes and colors. The sky is blue because of Rayleigh scattering. Blue light has shorter wavelengths than other visible light, so when the sunlight passes through the atmosphere it scatters more strongly in the blue part of the spectrum, resulting in the sky being blue.
