What color is the sand in Sahara?

The sand in the Sahara desert is usually light brown, beige or yellow in color, but it can vary depending on the location. The sand in the Sahara is composed mainly of quartz grains, with some feldspar, mica and other minerals. The color of the sand is determined by the composition and size of the grains. The light brown color of the sand in the Sahara is due to the presence of iron oxides, which give the sand its characteristic reddish-brown hue.
