An afterburner, also known as reheat, is an additional component added to some jet engines, primarily those on military supersonic aircraft or rockets. Its purpose is to provide a temporary increase in thrust, both for supersonic flight and for takeoff (as the high wing loading typical of supersonic aircraft designs means that take-off speed is very high). (From Wikipedia) Sometimes, it is used to slow down the aircraft to prevent big impact and cause deaths to passengers and pilots, so it will cause air resistance to the air.
Colorpedia finds out that this color doesn't match perfectly to the color. The color seems to sketch out the boundary of the afterburner which needs a very great eye to see the boundary.
Are you landing or taking off?
