30 Allah's Artistry In Colour

Prism

White light

The material densities, that is, the densities of atoms in space and of the atmosphere are
different from each other. For this reason, when light enters the atmosphere, it spreads
out more and becomes diffuse because it hits more atoms. The eyes of living beings can
see a colourful world only by perceiving these rays that come after being diffused, or in
other words, weakened by the atmosphere. In outer space environment where there is
no atmosphere, light is so strong as would harm the eyes. Apart from this, near infrared
rays also spread out in the atmosphere and warm the earth.

How, then, is this uninterrupted image made?
Passing through the atmosphere at enormous speed, light reaches the
earth and strikes objects. When light strikes an object at this speed, it inter-
acts with the atoms of the object and reflects at different wavelengths corre-
sponding to different colours. In this way, the book you are now holding, its
lines, pictures, the view you see when you look outside, trees, buildings, cars,
the sky, birds, cats, in short everything your eyes see, reflect their colours.
The molecules enabling these colours to be reflected are pigment mole-
cules. That is, the colour reflected by an object depends on the pigment mol-
ecules present in that object. Every pigment molecule has different atomic
structures. The atomic numbers as well as the types and the sequences of
atoms in these molecules are different. Light hitting such diverse pigments is
reflected in different shades of colour. However, this is not enough for the
formation of colour. For reflected light possessing a certain colour quality to
