The names of the things you want to change are called spines.

You want:

  ax1.spines['right'].set_visible(False)
  ax1.spines['top'].set_visible(False)
  ax1.spines['left'].set_color('red')
  ax1.spines['bottom'].set_color('red')
  #and so on for .set_linestyle, .set_linewidth

To hide the tickmarks that are right next to the spines, you can
do:

  ax1.xaxis.tick_bottom()
  ax1.yaxis.tick_left()

and finally, to color the ticks in red as well, do:

  ax1.tick_params(color='red')

best,
