A closer look

Airlines specifically choose to paint the vast majority of their passenger planes bright white because the color reflects sunlight, which significantly reduces the time and energy needed to cool the cabin on the tarmac. Darker colors absorb heat, meaning the air conditioning would have to work overtime just to keep you from roasting in your tiny economy seat before takeoff. Additionally, white paint is chemically lighter than most colored paints, saving hundreds of pounds in weight and subsequently millions of dollars in jet fuel over a plane's lifespan. Furthermore, a stark white fuselage makes it incredibly easy for mechanics to spot cracks, oil leaks, and other terrifying structural failures during routine inspections. So while it might look mind-numbingly boring, that basic white paint job is the only thing standing between you and an incredibly expensive, sweaty, and potentially disastrous journey through the sky!
