The sand in Bermuda is pink because it is made up of crushed coral and shells. The pink color comes from the shells of a type of marine algae called Foraminifera, which are found in abundance in the waters around Bermuda. When these shells break down, they release a pigment called “purpurin,” which gives the sand its pink color. The sand in Bermuda is also mixed with white and black grains, which gives it a unique, speckled appearance.
