Receivers pick up the rebounding waves, and software interprets the signals before displaying the information on a screen.

The yellow light that you described is likely an indication of a potential match in the TSA's Secure Flight system.
The scanner software recognizes metallic and non-metallic items hiding under clothing. The machine then processes an image using yellow boxes to point out any areas that may need additional screening.
By comparing the two detectors' outputs, the machine can construct an image showing not just the position of objects, but also roughly what they're made of and their density. Organic materials like paper, food and explosives are orange, while blue or green are used for metals and glass.
If there is a threat, a red box will appear on the outline at the location of the object. If there is no threat, an OK will appear on the screen without an outline. It will also allow the passengers to see what the TSA agents see when they step through the scanner.

These airport scanners can also detect gold because gold is a metallic object with low conductivity, so the high-frequency radiation of the scanner will see it easily. It is impossible to hide things from airport scanners in your belongings because the scanner gives a clear image of metallic objects.
