These are Photos taken from the anode and cathod of a device I'm making I removed all the light,, decreased white point, black point and increased saturation and contrast to get a better view of what was going on, hues and toes were left un adjusted.

Just wondering if the light is electromagnetic light or why the light is the coloring is.

Yes that light is photons just like ordinary light
The textbook has a chapter about LEDs. Scroll down to about halfway down of this chapter. I know it's there because I was the one that wrote it.

Lessons in Electric Circuits'

Side note: white LED's are actually blue/ ultraviolet LED's coated with a phosphor. Ultraviolet LED's are hard to find because they are slightly hazardous but are good for photo exposing resist on printed circuit boards. UV can damage your eyes.
