There is nothing special of the gold tint canopy in any aircraft. I am particularly talking about F-22 which is the one that people "discovered" the magical effect. All these canopies are coated with Indium Tin Oxide which at a certain angel to the incoming light would appear gold to the observer in a certain angel to the aircraft. There are many photos that F-16's canopy appears gold. There are also many photos that F-22's canopy appears that same as J-20 as the photo below shows. I suspect the reason of F-22 appears "unique" is USAF giving more PR attention to F-22 by employing artistical centric photographers.
These tinted glasses are commonly used in civilian application. Many fancy ski masks give gold, silver and rainbow effect.
