COLOUR , plays an important role in the appreciation of our immediate and general environment and without it we would be lost, find our-selves devoid of the stimulation to our visual senses. So how does a human eye perceive colour? First, a brief overview of how the human eyes work. In order for us to see, light rays must be bent, or "refracted," so that they can reach the retina . Once the light reaches the retina, it's picked up by millions of "photoreceptors," or light-sensitive cells, called cones and rods. These cones and rods convert the light waves into information your brain can process, like colour , shape, and motion.(Levine,2017, Para.2). Basically, rods interpret light, and cones interpret colours . Animals that are truly colour-blind completely lack cones, and animals that can only see during the day completely lack rods—but these extremes are uncommon , and most animals have a combination of cones and rods. (Levine,2017, Para.3). A schematic ...
