Assuming an open model of the universe and a long enough timeline galaxies which appear "normal" today would become more red shifted over the course of observation. I put normal in quotes because there are no galaxies which are relatively static to ours. Any galaxy which has movement will have some "shift" to them, and all galaxies are moving away from us.
It is possible that eventually the light from them could move into the infrared and even the microwave in extreme cases.
