The ability of a coating to conceal the underlying primer.

The main idea here is how well a coating covers up the color of what’s underneath. In automotive finishing, this is described as color hiding—the ability of the topcoat to mask the primer or any underlying color so you don’t see it through the new layer. A coating with strong color hiding has enough pigment and proper formulation to effectively conceal the primer, giving a uniform appearance. Gloss and texture don’t address concealment of the primer. Gloss is about how shiny the film is, and texture is about the surface feel or roughness. Opacity relates to how opaque the film is in general, but the phrase used to describe concealing what’s beneath is color hiding, which directly ties to masking the primer’s color in practice.
