Passing Variables

I went through the documentation but I am not sure I am understanding correctly.

My question is pretty simple.

If I have a formula file
an Inside COloring file
and OUtside Coloring file

Can I pass a parameter on the formula file to the coloring file... specifically the Color density?

Thank you for your help in advance!

This is not possible -- the fractal formula and coloring algorithms are independent and cannot share any information. This ensures that you can combine any fractal formula with any coloring algorithm.

Thank you so much!
