The reflections in the eyeballs are consistent for the real person, but incorrect (from a physics point of view) for the fake person. Image credit: Adejumoke Owolabi / CC BY 4.0.

$Optical manufacture of stretchable color-changing materials at the macroscale: (a) structural color patterns are recorded as periodic refractive index variations in the photo-elastomer via standing waves that result from exposure to a projected light pattern that reflects off the mirror backing; (b) the resulting structural color matches the spectral distribution of the exposure pattern; when the material is stretched or compressed, the periodicity of the recorded photonic structure changes, causing a predictable and reversible color change.
