Evolving Science Birds See In More ‘Color’ Than | Page 2

Human eyes are relatively effective at ‘seeing’ colors. The cells required to do so, known as cone cells,
are packed into our retinas in great perfusion. Therefore, we can convert light that bounces off the
objects around us into the various colors that they represent. Our cones come in red, green and blue
subtypes, but their activation is processed into hundreds of different shades based on the differing
proportions of these basic primary light colors that hit our eyes.
