This honestly seems like raw black magic. How is this possible?

  I mean, all color is is your brain's perception of 3 input channels. Your eye can detect (roughly) the amount of stimulation from blue light, green light, and red light... your brain interprets this as a color. You can do the same thing for X-rays, or any 3-channel data source. (Fun fact: because of this, there are colors that your brain can understand but aren't wavelengths of light. Magenta is seen when your blue and red sensors are activated... but there is no single wavelength of light that can do this. Meanwhile, your eye can't tell the difference between monochromatic yellow light, or red and green light being received simultaneously. This is why RGB monitors work, and why you can't represent every color you can see on a computer screen.)
