Which of the following is a type of colouring that can be added to spirits?

The correct answer is that both natural and artificial color can be added to spirits.

Natural color refers to food-safe colorings derived from plant or animal sources, which might include caramel coloring, beet juice, or other natural extracts that impart color without synthetic ingredients. These natural additives can enhance the visual appeal of the spirit while maintaining a more organic label.

Artificial color, on the other hand, consists of synthetic compounds designed to impart color and can be used for consistency and cost-effectiveness. These colorants might not be derived from natural sources, providing a more vivid and stable hue that can withstand the effects of light and temperature, ensuring that the product maintains its appearance over time.

Overall, producers have the option to choose either or both types of coloring to achieve their desired aesthetic effects for their spirits.
