I just added a line to set the color of the group to a random color -- 
works just as well:

on mouseUp
   local tNum
   local twID
   local tFol
   local tDest

   put the colorNames into tColors  --< NEW

   put 500 into tNum
   put the windowID of this stack into twID
   put "/Users/rg/Desktop/untitled folder/" into tFol
   set the defaultfolder to tFol

   repeat with x = 1 to tNum
     if the mouse is down then
       exit to top
     end if
     put x & ".png" into tDest
     put x into fld "counter"
     set the backgroundColor of grp 1 to  any line of tColors --< NEW
     export snapshot from grp 1 to file tDest as PNG
   end repeat
   answer "Done!"
end mouseUp

Then I added a graphic in case there was something specific to that 
object type, changing the color of the graphic instead of the group. 
Same good result.
