An excellent resource for this is "Digital Prepress for Comic Books" by Kevin Tinsley. Page 84 of my edition lists many suitable selections for people of color such as C20M50Y100, where "C" is cyan, "M" is magenta, and "Y" is yellow. Other selections are C10M40Y70, and C10M35Y40.
The problem is that if, and it's a large if, you intend to print your work you should consider the paper stock, the inks, and the printing press, lithography, roto-gravure, or some other process. All of these factors WILL affect the finished product!
