There are no “high resolution super x rays” at the airports. They are very low resolution x ray machines and the color you are seeing is for “post processing”. It separates organic and inorganic material in different colors to tell the difference. High resolution machines are not Xray machines but CT machines that allow a 3D image of the item to appear. They are very new technology and govt agencies such as TSA are just starting to depoly them across the US. They are two very different technologies and require different training.
Medical X-Rays are stronger and are designed to see through the body like u/Xelopheris says. Airport xrays are designed to look for weapon or bomb components.
