Diverging Binary and Diverging Sequential Color Schemes
Diverging/binary and diverging/sequential schemes have the same perceptual
characteristics. The success of the schemes hinge on the large contrast
range available in the lightness dimension. Large lightness steps are used
for the binary or sequential variable. Smaller lightness steps, that are
bolstered by a change in hue, represent the diverging component of the
scheme within each large lightness step of the comparison variable. For
example, data on cancer rates above and below a mean rate (diverging) and
air pollution levels (sequential) are well represented by a diverging/sequential
color scheme.
