The main reasons why civil airliners choose white as the standard color are:
1. More colors mean more weight, more fuel consumption and higher cost. In addition, the cost of painting the whole aircraft is between 50 thousand and 200 thousand dollars. At the same time, the whole spraying work takes 2 to 3 weeks, which will also cause losses to airlines.
Second, white can reflect light in all bands, which can reduce the heat generated by the fuselage, while other colors will absorb light in multiple bands and convert it into heat energy, which will cause the object to become hot. Therefore, keeping the fuselage low temperature can save fuel consumed by turning on the air conditioner.
Third, white helps maintenance personnel find fuselage defects and is easy to check. For example, if the pipeline on the plane leaks, substances such as hydraulic oil or fuel will leak out. The white fuselage will make these oil spills obvious, and the staff can easily find the problem. Secondly, when driving at night, the visibility of dark painted aircraft is poor, which is easy to cause collision accidents.

Other advantages of choosing a white body:
First, all color paints will face the problem of fading after being exposed to sunlight and air. Especially when exposed to 30,000 feet of air, a considerable amount of ultraviolet radiation will accelerate the whole fading process. After years of exposure, white can still maintain a good appearance. .
Second, in the process of buying, selling and leasing aircraft, white can leave buyers more room to play, and the cost of painting and maintenance will be lower. In short, whether it is safety or economy, white body is the best choice. Let's review an airplane painting event in history:
1996 Pepsi has reached an advertising agreement with Air France to spray Concorde in the color of Pepsi logo. It took the sprayers 2000 hours and 200 liters of blue paint to finish the job. In this way, the plane can only fly at the speed of M2 for 20 minutes, otherwise the beautiful painting may be scalded and peeled off, and Concorde will soon paint back to its original white main color.
