I'm not entirely sure what the alpha value has to do. I simply revert the unwanted behavior of #5596 i.e. in the function Line2D.draw(renderer), with the above setting, prior to the the change-set, at line 830, edgecolor (returned by Line2D.get_markeredgecolor())would be 'k', and after the call gc.set_foreground(edgecolor) on line 835, gc._rgb takes the value that I set. Will put a test case tomorrow to check to be sure that I did not miss anything.
