I'd like to have a color scheme for **printing** plots, that would look 'nice'. So, I need as set of, say, 10 easily distinguishable colors that would stay different when printed.

If I use only four CMYK colors they are easily distinguished. If I print ten, like blue, light blue, green, lime..., they may turn out very similar.

What tool (something like Adobe Kuler) can I use?
