How to Remove Background Color (PowerShell)

I was playing around with PowerShell today and added a background color to all text ...now I want it gone!

Anyone know how to do that, as a side note I was trying to change the color of the whole blank area that fills the application (formerly known as the background ..开发者_开发百科.good job Microsoft) so if you know how to do that please do share.
