Enhanced colormaps for help with color blindness and color deficient viewers

There's an interesting article on improving color maps for scientific visualizations entitled "The End of the Rainbow? Color Schemes for Improved Data Graphics". Click on the PDF file to download the article, or view some of the PNG files for comparisons of color maps. Several of the color maps below were taken with permission from this article.

Thanks to Andrea Hahmann and Joe Grim for bring these tables to our attention.
