Which type of color does not have covering power?

The correct answer is transparent. Transparent colors allow light to pass through, meaning they do not have any covering power. They are used for creating effects that show the underlying skin or pigment color underneath rather than obscuring it. This characteristic makes transparent colors valuable for techniques where a soft, subtle appearance is desired, such as in certain tattooing or permanent makeup applications.

Translucent colors, on the other hand, have some degree of covering power, allowing a moderate amount of underlying color to show through while also imparting their own hue. Opaque colors have full covering power and effectively conceal any underlying color, making them ideal for solid, bold applications. Metallic colors typically contain fine metallic particles but may also hold varying degrees of opacity. Their reflective quality is distinct but may not directly relate to covering capability in the same way transparent colors are characterized.
