Using a color palette or color gradient can considerably improve legibility, especially of 3D graphics. In 2D diagrams, color palettes are often used for presenting ranges of values, such as tolerance bands and warning ranges. Color gradients, especially spectral color gradients, which simulate the colors of a rainbow, form the basis for what is called a 2 1/2D graphics contour and color field matrix. Here, the information for the third dimension is marked by the color.

The assignment of the colors for color gradient or for the color palette to the scaling the Y axis in a 3D diagram is represented by its color legend.
