fulfilled for us to "see" any colour. The last stage in the formation of colours
is the interpretation of the electric signals, which arrive at the vision centre of
brain, as "colour" by very special nerve cells located there.
As seen, for the formation of a single colour, a very detailed and inter-
dependent sequence of processes is required.
All the information we have about colour indicates that every process
that takes place during the formation of colour is set on very delicate balances.
Without these balances, we would inevitably be left in a fuzzy dark world
instead of a clear colourful one, and would even lose our ability to see. Let us
suppose that of the above-mentioned items, only one – the nerve cells that
perceive the electric signals generated by the retina – does not exist. Neither

the sunlight being within the visible spectrum, nor the other parts of the eye
being completely functional, nor the existence of the atmosphere would be
adequate and compensate for this lack.

The Role of Retina in Seeing
Let us examine the retina closer and in more detail. Let us suppose that
the pigmentary substance called "rhodopsin", operating in the retina, is
absent. Rhodopsin is a substance that ceases functioning under heavy light
but is regenerated in darkness. The eye cannot see clearly in dim light unless

sufficient rhodopsin is produced in the eye. The function of rhodopsin is to
increase the efficiency with which the eye generates a nerve impulse from
dim light. This substance is produced as much as required exactly when it is
needed. When the rhodopsin balance is maintained, images become clear.
What would happen if rhodopsin, which is very significant for the process of
sight, did not exist? In that case, man would be capable of seeing only in
2
bright light. It is therefore evident that there is a perfect system within the
eye, which has been designed down to the smallest detail.
Then, whose work of art is this system, which saves us from darkness
and presents us a world full of colour?
