For me, resetting cmd-prompt to default colors did not work in IntelliJ 15. It still had old cmd-prompt colors since IntelliJ was installed.
In this case, you can go to File β Settings β Tools β Terminal and enter "cmd.exe / T: 07" as the Shell path option. This will launch the terminal and reset the color to the default black background and white font.
BTW: this way you can save your favorite color settings in the cmd command line.
