Why are drones grey?

The question pops up every couple of years

Drone colours - why?

There may be a good reason for the bland colours. When colours are added to plastic mouldings they often become harder and more brittle. It also increases manufacturing costs. A drone is subject to a lot of stresses in flight, and the body needs to be able to flex constantly, prior to being dumped on the ground at the end of a flight, which can be enormously stressful on the drone and pilot! Being able to absorb some of the energy also helps to protect the sensitive electronics.
