So much is conveyed through the use of color in our existence. Birds with their mating plumage, flower petals, women in their 'war-paint' and the possibilities are endless.
Here is where I like to insert the analogy of people and color. The shades of a person are a varied as the palette in nature. Think about it, what we see as our self may or may not be the 'shade' another person sees in us.
The absence of heat is cold. So what is the absence of color in nature? What do you call the lack of seeing color, shades, nuisances in people?
