The reflectivity corresponds to the material's ability to send the scanned laser light.
The reflectivity depends on the material (eg in descending order: steel, aluminum, iron, concrete, asphalt, graphite), color (eg descending: white, yellow, green, red, gray, black), and its coating Glossy or matte.

In the cloud point, the reflectivity is often represented by a color gradient from yellow to red.
