And God said, Let there be light: and there was light.
Genesis 1:3
"The color of an object is the result of interactions between incident light and this object as well as between the light sent back by the latter and the visual system of an observer. *The diversity of colors in the living world results essentially from differences in pigment composition and the surface microstructure of plants and animals.
*It is also dependent on the way the observer perceives colors.
*Finally, to a lesser extent, variations in the ambient light might play a role."
