Is there any way to make formula variables visible in the coloring formula loop? I'm trying some fractals with more than one variable z and need to use both in coloring.

I have an ugly workaround basically doing all the coloring in the fractal formula and stuffing the color index in #z at the end and then just setting #index = #z in the coloring formula.
