It's said that (for those of us with full visual faculties) we process something like 80% of what we learn visually. Color-coding, shading and graphs are some ways of marking differences between between values and degrees of value, helping us digest large amounts of complex information in a single glance. Consider the political map, with each country, state, county, or other subdivision in a different color. "Red" states and "blue" states. Degrees of obesity per state. And so on.
Consider the color-coded diagram of the human digestive system. Red stomach, yellow intestines, pink colon, green gallbladder, brown liver. What color is your pancreas? Do you want to color it in World Diabetes Day blue to indicate yours has died?
