TFT Display with ILI9341 running

drawing is done like this

  graphics.setColor(0,1,0);
  graphics.fillRect(70,70,120,100);
  graphics.setFontVector(12);
  graphics.drawString("Espruino",0,0);

inside my module graphics are created like this:

              me.graphics = Graphics.createCallback(240,320,16,{
                setPixel:function(x,y,c){setPixel(x,y,c);},
                fillRect:function(x1,y1,x2,y2,c){fillRect(x1,y1,x2,y2,c);}
              });

And fillRect is doing this:

  function fillRect(x1,y1,x2,y2,c){
console.log(x1,y1,x2,y2,c);

which returns this:
70 70 120 120 undefined
2 11 2 12 2016
3 10 3 12 2016
In my best understanding:
drawing rects from drawString send color as 5th parameter
same from fillRect does not use the color parameter
