In reading, Robert Simmon shows a variety of relationships between colors and human. We invent computers to help us to analyze colors. Before we have computers, we mostly use our intuition to distinguish colors. Most of color selections are inspired from nature and the environment around us. These selections may not be accurate but usually can be accepted universally. Using computer as a tool to make colors gives a wide new world to chose colors. During that process, we can choose color from a non-visual start point but from numbers and methods. Combining intuition and computer methods could provide a precise and acceptable way of choosing color representations.
