Within the reading, Subtleties of Color, Robert Simmon touches upon the difference between the way we see color versus the way computers sees color. Though computers reads color in a linear way, our eyes can not perceive it like so because some colors look brighter to us than others. Thus, there are ways that people have organized color to allow for us to view it as a progression even though computers see them differently. This is very important especially in terms of representing data as colors are often used to represent or draw attention to something. Having control over how people perceive the colors allows for better visualization methods as well as representation.
