             Rays from the Sun consist of particles known as “photons” that move by wave
             motion. When photons strike the electrons of atoms that make up the matter on
             Earth, they give off light at a particular wavelength “that express color.” For exam-
             ple, when sunlight falls on a leaf, the photons strike the atoms of the pigment mole-
             cules on the leaf surface. The effect produced by this collision sets the electrons in
             the atoms of the leaf in motion. As a reaction to this collision motion, atoms send
             photons off to the outside. The “color” that photons thus produce heads to our
             eyes.


             and extremely complex vision area, the eye, as a whole, has a very special
             structure, the existence of which cannot be attributed to coincidence.

                 After a short introduction to the eye, let us also look at how the event of
             seeing takes place. Light rays coming to the eye first pass through the cornea,
             then the pupil and lens, and finally reach the retina.
                 The perception of colour begins at the cone cells in the retina. There are
             three main cone cell groups that strongly react to certain colours of light.
             These are classified as blue, green and red cone cells. The colours red, blue
             and green, to which cone cells react, are the three primary colours existing in
