Red Sand Beach (also known as Kaihalulu) is located in Maui, Hawaii and is a pocked beach, partially isolated from the ocean. Because this area is rich in iron, the sand has a red-black color which makes a great contrast with the water.
Pink Sands Beach, Harbour Island, Bahamas. "Harbour Island is just 3.5 miles long and 1.5 miles wide, but this tiny slice of the Bahamas has one of the Caribbean’s prettiest beaches: three miles of pink sand that stretches along the island’s east coast. The red shells of foraminifera—single-celled marine animals—mix with the island’s white sand, thus creating the soft rosy hue."
