Paint matching is the process of finding a paint color that closely resembles an existing color. This is often done when homeowners want to touch up walls or furniture without repainting an entire area. Professionals use tools like color spectrophotometers to analyze the original color and create a matching formula. To achieve a perfect match, paint stores may also use physical samples, such as a chip or swatch, to compare colors. Once the right shade is identified, it can be mixed using various paint types, ensuring that the finish and texture align with the original surface.
