Setting color of checked toggle button

[moz]

My first foray into Qt land using python and pyqt. I've created a toggle button and I'm able to set its unchecked colors:

self.DCButton.setStyleSheet("color: black; background-color: red;")

self.DCButton.setStyleSheet("color: black; background-color: red;")

To copy to clipboard, switch view to plain text mode 

My problem is setting the button color when its "checked":

self.DCButton.setStyleSheet(QPushButton#DCButton:checked {"color:black; background-color: green;}")

self.DCButton.setStyleSheet(QPushButton#DCButton:checked {"color:black; background-color: green;}")

To copy to clipboard, switch view to plain text mode 

doesn't work. I'm sure this is a simple syntax problem.

TIA
