For all creative people: Mandelbrot coloring ... need ideas

Given the maximum number of iterations = 1000, give me some ideas on how color (red, green, blue). All I can do right now is lame color gradients :(

Is it possible to come up with something beautiful like this?

The 50 iterations are very, very crude, and you won't get the details.

The easiest way to get the spectrum is to use several two-color gradients. Thus, 50-41 iterations can be shades of blue, 41-30 it can be blue-red, and 29-10 it can be red-green, and 9-0 it can be green-white.

I’m just wondering what would happen if we knit different colors not only for different speeds of divergence, but also for different speeds of convergence. I think that inside would be much nicer than just black.
