Combining colors in particular ways can convey subtle nuances of meaning. An analogous color scheme uses colors that are adjacent on the cob:
wheel, such as green, blue-green, and blue. Although this type of cobo’ scheme shows the differences among the components represented, it also suggests their connection and compatibility. For example, a pie graph could use analogous colors to represent the students, faculty, and administration c.f a university. The different colors suggest that these parts are indeed separate but the analogous color scheme and the inclusion of these parts within circle imply that they belong together. In this subtle way, the presentation aid itself makes the statement that the components of a university ought t:
work together.
