Hi all,
I have a collection of molecules and want to color a particular helix (in cartoon mode) a specific color different from other helices.  Unfortunately, I had previously set cartoon_color from "default" to another color, so now specifying a color for that helix (or even "color red, ss h") has no impact.  (it does change the color of the Calpha, but not the cartoon itself). 
So, the question is, how do I unset the cartoon_color variable (without wiping out my scene)?  The variable setting comes with the .pse file, "set cartoon_color, default" gives an error about not knowing what color default is.
