ЦитатаStill, a light grey color was found to be about as effective. Throughout the 60s and 70s, more and more military aircraft were painted in what is now called low-visibility grey. This color is similar to that of a cloudy sky, or of the haze that often covers distant objects.

How the F-117 came to be painted black is an interesting story. Even at night, black is not as good as dark grey for blending into the background. Stars and the moon provide some light, and a shadow against them is noticeable. In areas with more light pollution, where stars are hard to see and moonlight does not add much to ambient illumination, a black shape moving through the sky is also noticeable. The air illuminated at night over cities (especially when cloudy) would also make a black aircraft stick out like a sore thumb, while a grey aircraft would blend into the clouds. For non-light-polluted areas where the stars can be seen at night, an almost-white color might actually be least visible. When the F-117 was being test-flown, Lockheed engineers researched all this, and presented a report to the US Air Force suggesting that their new stealthy fighter-bomber be painted the standard low-visibility grey with a very light grey belly. The commanders in charge of the F-117 program, however, thought that the F-117 could never survive daytime operations, and decided that painting them black would prevent mission planners from ever deploying the F-117 outside the cover of night. So it was painted black not for stealth, but so that the aircraft would not be flown through undue risk. However, in late 2003, some F-117s were finally painted in low-visibility grey, and (just as the commanders feared) were evaluated for daytime operations.

Why the choice of colour?
He explained the new look has nothing to do with making the Jetstream stealthier.
Jason said: “Quite the opposite in fact, the colour has been chosen to make it easier to see which I believe is why all our Hawk training aircraft are painted black.”
