Sure, you can use a fit function inside an attributeWrangle, and force the result into an integer.
Make sure to run over Primitives, not points, assuming you have packed primitives.
int color_index = int(fit01(rand(@primnum),0,3));
if (color_index == 0){v@Cd = set(1,0,0);}
if (color_index == 1){v@Cd = set(0,1,0);}
if (color_index == 2){v@Cd = set(0,0,1);}

Thank you very much, thats really helpful! Just to let you know I wanted each geo to have its own colour, not each primitive, so I changed your code to @class instead of @primnum after I added a connectivity node before the wrangle. Again thanks man
