Diverging Color Schemes
|Blue-to-Dark Orange, 18 Steps
||Useful for data without a
specific subjective color association.
Sequential Color Schemes
Categorical Color Schemes
Simulations of the appearance of the color schemes to color-deficient
viewers were based on algorithms in
Designing for the
Color-Challenged: A Challenge
T.G. Wolfmaier, Internetworking 2.1 (Internet Technical Group
Newsletter) March 1999
Thomas Wolfmaier's discussion of the issues arising in designing for
color-deficient viewers. Includes a Java application demonstrating the
simulation of how different kinds of color-deficient viewers may perceive
particular colors specified by the user.

Hans Brettel's applets for simulation the appearance of colors to
color-deficient viewers. See also H. Brettel, F. Viénot, and J. D.

The categorical color scheme above, as well as inspiration for some of
the other schemes, comes from
Cindy Brewer's web application that demonstrates sequential, diverging, and
qualitative color schemes (and provides the specifications of those schemes in
several different color spaces). See also: Brewer, C.A., G.W.
Hatchard, and M.A. Harrower, (2003), Colorbrewer in print: A catalog of
