Pictures of visible light are characterized by their ability to be seen by the human eye.

These pictures are typically vibrant and clear, showcasing the visible spectrum of colors from red to violet.
"If an eye had absorbed all light, then this wouldn't happen. In fact, if an eye had been theoretically flawless, the red eye effect would not have existed at all. What happens when you see the red eyes on pictures, is that the flash is reflected in someone's eye. The reflection is red because of all the blood vessels inside the eye." -http://photocritic.org/red-eye-removal-reduction/

Yes, individuals with lighter eye colors, such as blue or green, may be more prone to red eye in photos because their retinas are more visible due to less melanin. This increased visibility of the retina reflects the light from the camera flash, resulting in the red-eye effect.
