As a color-blind climatologist, I very much appreciated the important color-awareness issues raised by A. Light and P. J. Bartlein in their recent Eos article titled The End of the Rainbow? Color Schemes for Improved Data Graphics, (85(40), 385, 5 October 2004). Meteorological and climate information is frequently communicated in the form of highly colored spatial maps (e.g., daily weather forecasts). The use of color is so endemic in climate research that it would be unthinkable to present scientific work at a climate conference without using color! The color schemes generally chosen to create such maps follow no universal convention and often consist of colors that cause confusion to both color-impaired and non-color-impaired people.
