The best introduction is Gooch & Gooch on Non-Photorealistic Rendering. That
has got a good chapter on simple brush dynamics. Salesin et al introduced
using a spectrometer to figure out how to properly mix colors in their paper
http://citeseer.ist.psu.edu/curtis97computergenerated.html. This is available
on-line, but if you cannot find it I can mail you the pdf as soon as I'm home.
The most impressive results can be found in Bill Baxter's articles and thesis
Plus, Bill Baxter is a very good and clear writer: 
http://www.billbaxter.com/projects/index.html. A large overview of the
field is given at http://www.red3d.com/cwr/npr/.

Have fun!
