Which term describes a coating's capacity to obscure the primer color?

Color hiding describes how well a coating masks or conceals the color of the primer underneath. In automotive refinishing, you want the topcoat to read true to its own color, without primer tint showing through. This depends on the pigment load and hiding power of the finish, so a coating with strong color hiding will obscure the primer color and produce a uniform final appearance. Opacity is related—it’s about how opaque the film is—but opacity is a broader property of the coating, not the specific function of masking the primer. Gloss level concerns shine, not color masking, and compatibility is about chemical compatibility between layers, not how well the primer color is hidden.
