As the examples in Figure *** also demonstrate, color is a commonly used (and possibly abused) visual variable to express patterns. The use of color will change everything! The number of colors we use, or whether we use sequential versus diverging colors, will change what we see in the visualization; thus what we believe about our data’s content. Even though seemingly not widely known outside the visualization community, many examples of how color choices impact visual analysis has been demonstrated. Most frequently referred example is possibly Rogowitz & Treinish’s 1996 paper (see an example in Figure 4).
