Shining light directly on the face of an animal with a tapetum lucidum causes the eyes to glow. Eyeshine comes in various colors, including white, yellow, red, blue, pink, or green. Since the reflective layer is iridescent, the pupils' color is affected by the angle of vision, eye color, and the mineral makeup of the tapetum lucidum.
