Identify at least two advantages and two disadvantages of using color to visually represent information.
What will be an ideal response?
Advantages: Color makes it much easier to visually distinguish visual el-
ements from one another. For example, three clusters of two-dimensional
points are more readily distinguished if the markers representing the points
have different colors, rather than only different shapes. Also, figures with
color are more interesting to look at.
Disadvantages: Some people are color blind and may not be able to properly
interpret a color figure. Grayscale figures can show more detail in some cases.
Color can be hard to use properly. For example, a poor color scheme can be
garish or can focus attention on unimportant elements.
