Planes are nearly always painted white. There are several reasons for this:
- Heat reflection. If an aircraft is painted white, it accumulates less heat. This is better for passengers and economically profitable for airlines.
- White paint is less expensive. While paint is way cheaper than other paint.
- Preventing collisions with birds. Birds can see the reflection from white surfaces better and don’t often collide with airplanes for this reason.
- White paint helps reveal even small cracks and dents. White details are easily recognized in case of an accident and it’s easier to notice damages.
