Questions about color white/black

Hello All,

For color white/black, it might be swapped with difference display style/background color, and it might changed if open same drawing with MS V8i/CE. I'd like to know if there any way to let the color white/black at any circumstance. It is not have to be exactly white/black(RGB0,0,0/255,255,255), it is acceptable if the color is pretty close. I have tried to use the color 1,1,1/254,254,254, but the result is same. I created QRcode by shapes, so the color white/black must be unchanged. Thanks a lot.
