I don't understand color systems very well, either, but I ran into this problem when I printed out some color figures recently. I saved a mpl line plot containing 'r', 'g' and 'b' lines to a PDF file. The file displayed on-screen as expected, using both Linux acroread and Mac OS X Preview as viewer. It also printed out as expected on an HP Color Laserjet via Linux acroread. On the Mac, however, a straightforward printout resulted in purple instead of blue lines. The problem disappeared when I selected ColorSync -> Color Conversion -> In Printer in the print dialog. When I printed out an OmniGraffle PDF diagram, however, the colors were messed up using "In Printer" and correct when using "Standard" color conversion. This forced me to print the color pages in my thesis containing OmniGraffle diagrams and mpl figures using different printer settings, which is quite annoying. There is another option, which makes Linux and Mac PDFs much more compatible (especially for color), and that is PDF/X-3 (http://en.wikipedia.org/wiki/PDF/X). This subset of PDF forces the document to include all fonts and color profiles, leaving nothing to chance. While the file is possibly bigger, it is more likely to display correctly on all manner of printers and screens. I eventually converted my Omnigraffle diagrams to PDF/X-3, and now their colors and shadows appear correct on Linux, while they were psychedelic before. PDF/X-3 might be a worthwhile standard to follow for mpl figure output (even only as an option). At least embedding ICC profiles is probably a good idea.
