Well when it comes building of machine prices also matter, nobody want to lose in a business, apart from the radiation aspect.
Paint have thier own weigh also, some paint have more weight that the other. So if any other colour of paint is used to paint an aeroplane it will be adding more weight to the aeroplane, meaning more fuels will be burnt to power such an aeroplane. So must aeroplane compare prepare the white color. And when some of these aeroplane have reach their end of life, it can be easily sold to other aeroplane company without the need of repainting.
