Aircrafts and commercial airliners may carry colourful stripes or bold patterns, but one feature remains almost universal: a white base colour.
While it is technically possible to paint an aircraft any colour: from green to gold: white has become the industry standard for private and commercial aviation.
When aircraft first roll off the manufacturer’s assembly line, they are usually green, coated in a zinc phosphate primer. This is why test aircraft often appear green during flight trials. Although there is no technical requirement for them to be repainted, most are finished in white before delivery.
Industry experts say there are several reasons why white dominates aircraft design.
Thermal efficiency
White reflects most sunlight, unlike darker colours that absorb heat. This helps keep aircraft cabins cooler, especially on hot runways, and in some cases helps manufacturers stay within airframe temperature limits.
A branding blank canvas
A white fuselage provides the ideal backdrop for logos and branding. While some manufacturers and operators use bold colours for marketing—such as HondaJet’s distinctive design—white remains the preferred base.
Higher resale and charter value
White aircraft generally retain higher resale value. New owners can easily add their own livery without paying for a full repaint. The same applies to charter aircraft, where neutral colours appeal to a wider range of clients.
Better ageing and lower repaint costs
White paint resists fading better than darker colours exposed to high-altitude sunlight. As a result, white aircraft often need repainting every four years instead of every two: an important factor when repainting can cost between $100,000 and $350,000.
Improved safety and maintenance
Cracks, corrosion and oil leaks are easier to spot on white surfaces, making inspections more effective. Although white aircraft may show dirt more easily, cleanliness also improves fuel efficiency by reducing drag.
Visibility in the sky
White aircraft are more visible in the air and at night, improving safety. This contrasts with military aircraft, which use camouflage colours to avoid detection.
Lower cost and tradition
White paint is widely available and cheaper than specialty colours. Beyond cost, research shows passengers feel more comfortable and secure flying in traditionally painted white aircraft.
