Though there are exceptions, planes are usually all white or white for the most part. Since your attention has been drawn let’s get to know why.
The first and most important reason has to do with thermal science. According to the Massachusetts Institute of Technology’s (MIT) Aeronautics and Astronautics professor R. John Hansman, white reflects the most sunlight hence, helps in keeping the cabin cool. It also cools the plastic and component parts, because they could be melted.
The color sort of acts like sunblock for dangerous solar radiation, as well. Then, there’s the birds. According to a 2011 study, birds collide less often with white airplanes compared to deep and light blue planes, which aren’t quite as easy to pick out of the sky. The color also makes it easier for humans to pick out cracks, dings, and divots that need repair.
The rest of the reasons all have to do with money. It takes up to 65 gallons of paint to coat one plane and white is a standard color, which makes it cheaper. Not to mention that colors will oxidize and fade, meaning you’d have to repaint more often in order to keep it bright. White planes sell faster than colored ones, as well, for all of these reasons.
