Hey - are you still interested? ;-)
I saw your posting regarding color palettes within Gnuplot.
If you are interested in data analysis and visualization, you might also be interested in my book “Gnuplot in Action”, which has a chapter specifically on color usage for data visualization, including some recommendations for optimal palette design. You can pre-order it directly from the publisher: Manning: Gnuplot in Action.
If you want to learn more about the book and the author, check out my book page at Principal Value - Gnuplot in Action.
Let me know if you are interested in a review copy.
