Coloring algorithms

Hi all,

i am currently writing my own fractal images generating program and i am
wondering how to color them.

I used the normal escape time algorithm, which works. Then I used the
renormalizations which smoothes them.

I read about others (3D coloring, coloring by Statics and Cuvature
Estimation). Are there any known algorithms? Maybe even C++ code?

Thanks, Regards
Christian
