What is sea shells colors?

Sea shells come in a wide variety of colors, ranging from white and cream to varying shades of brown, green, pink, blue, purple, and black. Some shells have intricate patterns and designs, while others are more solid in color. The colors of sea shells are usually determined by the type of pigments present in their shells, and the environmental factors that influence their growth. For example, the white color in shells is often caused by calcium carbonate, while red and pink colors are the result of pigments called porphyrins and carotenoids. The UV light and temperature of the water can also affect the shell colors. Additionally, some shells change color as they age or grow, making it possible to find different colors of the same species in a single area.
