Therefore, colour is not
an intrinsic property of the object, since if the light source
is changed, the colour of the object also changes
(Melendez-Martinez, Vicario, & Heredia, 2005). The perception
of colour is a very complex phenomenon that depends
on the composition of the object in its illumination
environment, the characteristics of the perceiving eye and
brain, and the angles of illumination and viewing.
