The ingredient in nail polish that serves as a colorant is pigment. Pigments are finely ground color particles that provide the nail polish with its hue and vibrancy. They are crucial for creating a wide variety of colors and shades in nail products, making them a fundamental component of any nail polish formulation. Pigments can be derived from organic or inorganic sources and determine not only the color but also the opacity and finish of the polish.

In the context of nail polish formulation, solvents help dissolve the ingredients and aid in the application process, adhesive components help the polish adhere to the nail, and binders often improve the durability and consistency of the polish. However, none of these components provide the color; that role is specifically fulfilled by pigments. This distinction is important for understanding the chemistry of nail products and the role each ingredient plays in the overall effectiveness and appeal of the polish.
