Apparently, the color of the beach is influenced by the components that make up the sand. There is sand that comes from earth minerals, metals, volcanic rocks and even shell fragments of marine life.

Here is an explanation for the 4 types of beach sand that you may have encountered:

White sand beach

The color of the white sand beach is really white like chalk. The components that make up white sand are quartz (the building blocks of glass) and lime, and may also contain other minerals such as feldspar and gypsum. One of the beaches of this type is in Hyams, Australia.

Tropical white sand beach

Although both white sand but the composition is different. On tropical islands, the sand is composed of calcium carbonate from marine organisms, such as coral reefs and shells.

Pink sand beach

Like a tropical white sand beach, the sand on this beach also consists of calcium carbonate derived from marine life. This beach gets its pink hue from the broken coral reefs.
