Using the configuration panel in Player, you cannot change the background or Medium color. The settings allows you to change the colors, and then displays them in the settings window correctly, but they are not applied to the simulation.
And, when you change the window color in settings, the change color dialog comes back after clicking on the "OK" button. It then shows the changed color in the dialog and you have to hit "OK" again.
Exiting and restarting Player also does not show the correct window color, but the changed window color is shown in the configuration panel.
