PlatformIO Serial Monitor black char on black background

when I click on my ATOM PlatformIO Home 0.6.0·Core 3.5.1a1on the Serial Console, I do get a consol which looks like my console on my Apple MAC but all output which came from my board is black. The background as well. So black char on black background does not work very well. Where can I change the color of the serial console ?

Did you change default colors for your system terminal?
