You should play with randomseed, the starting color (here white) and the
randomization amplitude (1,1,1).  You mileage may vary.

\starttext

\startMPcode
  for i=0 upto 3 :
      for j=0 upto 3 :
          draw unitsquare scaled 4cm shifted (4*i*cm,4*j*cm) ;
      endfor ;
  endfor ;
  for i=0 upto 4 :
      for j=0 upto 4 :
          label.llft(char(i*5+j+ASCII "A"), (4*i*cm,4*j*cm))
              withcolor white randomized (1,1,1) ;
      endfor ;
  endfor ;
\stopMPcode
