Almost all planes are white in the world but have you ever thought why? This is not just random decision rather this white color decreases the expenses of the passenger carrier and increases the safety of the flight.
The white color is selected because of reflects sunlight and solar radiation. This results in cooler cabins which mean that the cooling system can make the cabin cool with less energy.
Over 65 gallons paint is used on each plane to protect it from radiation, especially the fiber and plastic components which cannot sustain higher radiation and temperature.
The white color also protects some parts of the aeroplane from being destroyed through the excessive heat and temperature. This is why the white color has become common among all planes no matter in which country they are being manufactured or used.
