The human eye is one of the most intricate, complex organs of the body.  As light enters the iris, it is projected through the lens, onto the retina, which is on the back of the eye.  Unlike other species, this thin strip of cells which we call the retina has the equipment to see a wide range of color.  We have special photoreceptor cells called cones, which specialize in helping us see in color.  Without these different, specialized cells to code what we see and send electrical impulses to our brain, we would not be able to see in all of the vibrant colors that we do.

 
How do we know this?   Through research on colorblind humans, as well as colorblind animals, such as dogs, and cats, we have been able to identify the function of these small photoreceptor cells.  We have evolved to see a range of colors that we often refer to as the rainbow, or, the visible spectrum.  

The reason we see in this way, as opposed to cuttlefish, which can see in the ultraviolet spectrum, or dogs, who can see only limited colors, is that being able to see these colors has been advantageous to our survival as a species.  It is good for us to eat foods with vibrant color and many different colors, because their color is a code for which type of nutrients they possess. 

However, color is much more than a tool for survival – it is a tool for enjoyment.  We would not be feeling fulfilled if we saw everything in bland tones or grayscale.  Our eyes crave variety, which explains why we spend money picking particular clothes, cars, jewelry, flowers, and everything in between.  Why, then, would it make sense to have a house or an apartment with dull, drab walls?  Color is a feast for your eyes.  Call one of our interior painters today for a free painting estimate, and we'll help you pick out a great shade for your house.  Feed your eyes – it's good for you!
