Hidden Treasure is a perfect finish for those that desire a reflecting pool. The watercolor hue cast by black bottom pools can be either blue or green. Because of the intense color, they are highly influenced by their surroundings and sunlight. Random white pebbles are inherent in this product. View our disclaimer page to set proper expectations.
