Appendix
1. Color
There are three elements to observing color: lighting source, object, and observer. Changes in any of these three
will affect the color perception of the observer. When the lighting source and the observer do not change, then the
object will determine the color perception formed by the observer.
The reason why an object can affect the final color perception is that the reflection spectrum (transmission
spectrum) of the object modifies the light source spectrum. Different objects have different reflection spectra
(transmission spectrum). (Spectrum) modulation to obtain different results, because the observer does not
change, so it presents different colors, the principle is shown in the figure below.
