Understanding how color builds up with multiple coats is crucial for an exact color match. Let-down panels are test panels sprayed with varying amounts of midcoat so you can visually compare how different coat counts affect shade and depth and determine the exact number of coats needed to reach the target color. This approach directly shows the building effect of the midcoat under the same base and clear system and lighting conditions used for the final job.

A general test panel is a broad sample used for trying finishes, but it doesn’t specifically measure how many coats of midcoat are required. A color swatch is a fixed color sample, not a sprayed test showing coat-build-up. A color ramp presents a gradient of colors, not actual coated panels to compare with the target shade.
