   That's an interesting question.  I suppose you could theorize that   
   anything which is less than 3* 128 (384) is too dark for black.   
   Anything equal or greater is OK for black.  That might need some   
   tweaking.  If you have ProView, use the floating color selector to   
   experiment, but I expect it would hold, once you'd found the dividing   
   line...   
      
   Of course, colors are integers and it would probably be easier to   
   compare the color to an integer.  128,128,128 is 8421504.  And the   
   integer is smaller as you get darker and larger as you get lighter, so   
   the same theory should hold...   
      
   FWIW,
