Color perception
begins in the cone cells
in the eye’s retinal lay-
er. In the retina, there
are three main groups of cone cells, each of which react to particu-
lar light wavelengths. The first of these three groups is sensitive to
red, the second to blue, and the third to green. As a result of these
three different groups being stimulated in different proportions,
millions of different color shades are perceived. However, it is not
enough for light to reach the cone cells in order for us to see colors.
Jeremy Nathans, a researcher from the Johns Hopkins
University School of Medicine, states how the cone cells in the reti-
na do not actually give rise to color:

All that a single cone can do is capture light and tell you something
about its intensity . . . it tells you nothing about color. 36
These color data perceived by the cone cells are converted in-
to electrical signals, thanks to the varying pigments they possess.
The nerve cells connected to these cells then transmit these signals
to a special region in the brain, in which forms the vivid world we
see throughout our lives.
