Try this -

int k;
LabelField l;

GridFieldManager grid = new GridFieldManager(9,4,0); //First parameter for row,second for column
    for (int i = 1; i < 37; i++) {
        k=i%2;
         if(k!=0){
             l=new LabelField(""+i)
             {
                 public void paint(Graphics graphics)
                 {
                 graphics.setColor(Color.RED);
                 super.paint(graphics);
                 }
             } ;
         }else{
             l=new LabelField(""+i)
             {
                 public void paint(Graphics graphics)
                 {
                 graphics.setColor(Color.BLUE);
                 super.paint(graphics);
                 }
             } ;
         }

         grid.add(l);

    }
     grid.setColumnPadding(30);
     grid.setRowPadding(30);
     add(grid);
