Abstract
A process for producing a total match metric for matching color and appearance of a target coating and at least a specimen coating is provided. The total match metric (TMM) are produced based on color difference values (ΔE) at three or more color viewing angles, sparkle difference values (ΔS) at one or more sparkle viewing angles and flop difference value (Δf) between the target coating and the specimen coating using one or more linear functions, one or more non-linear functions, or a combination thereof. The total match metric can be used in producing matching coatings that match color and appearance of the target coating. The total match metric can be particularly useful for repair coating damages to vehicles.
