We used this in the ggobi book, www.ggobi.org/bookwww.ggobi.org/book. But otherwise the color palettes are meant for geographic areas rather than data plots. Good color choice is still an issue for point based-based plots. The R packages colorspace,colorspace and dichromatdichromat are useful. colorspacecolorspace allows selection of colors around the wheel,: you can spend hours/days fine tuning. dichromatdichromat helps check for colorblindness. ggplot2ggplot2 generally has good defaults, although not necessarily color blind-blind proof. The diverging red to blue scheme looks good on your computer but does not project well. I like the Dark2 palette from colorbrewer for scatterplot plots.
