This image shows what the FractalWorks program can do with colors. This image is colored using 4 separate color gradients. See the following image @ http://upload.pbase.com/duncanc/image/75494021 for a diagram of the colors used for this image.

If you have FractalWorks version 0.4.8 or later, you can recreate this plot by clicking here: Fractalworks plot Julia (large) blues & grays

If you have Fractalworks version 0.4.0 to 0.4.7 the plot should display but the colors will look different.
