I suggest using the rand() function (assuming you're using POV 3) combined
with a switch (too tired now to check the syntax in the docs, but sure it
lays there):

#declare loop_iterator = begin_iterator
#while (iterator < end_iterator)
  #declare A = rand()
  #declare B = rand()

  #switch (A)
    #range (0,0.25)
    #declare cx = colour Orange
    #break
    #range (0.25,0.5)
    #declare cx = colour Green
    #break
    #etc...
  #end
  #switch (B)
   #same here
  #end

  #sphere { ... texture { pigment { colour cx } } }
  #sphere { ... texture { pigment { colour cy } } }

  #declare iterator = iterator + increment
#end // #while ()

Happy ray-tracing,

B-o-b.
