The Color of Objects
Date：2016-12-02
There
are three major elements to perceive color: light, object and observer.
Any change of these three elements will influence the observer’s color
perception. When the light source and the observer don’t change, then
the object will determine the observer’s color perception.
Objects
can affect the final color perception because the reflectance spectra
(transmittance spectra) of the object have modulated the light source
spectrum. Different objects have different reflectance spectra
(transmittance spectra). The light source spectrum modulates the
reflectance spectra (transmittance spectra) of different objects to
obtain different results. The observer is the same, so it shows
different colors. The theory is shown in the figure below.
