PyQt5 - Emit Signal and Change color Font?

I have a Python application whereby I pass an object through to a QThread, where a signal is emitted back to the UI in a loop.

I am wondering if it is possible to emit a signal back to the main loop, and amend the font color depending on the returned value?

For example:

In the QThread Class...

if self.status != "True":
    # Set State
    state = "Failed"
    result = "Fail"
    reason = "I/O Failure"

    # Emit State
    self.state.emit(state)
    self.result.emit(result)
    self.reason.emit(reason)

    sleep(1)
else:
    print("All is Good")

From here, if the result is Fail, then I would like to amend the color to Red or color the Background of the QTableWidgetItem Cell a light red or similar, previously, I have done this as such...

status.setForeground(QtGui.QBrush(QtGui.QColor('red')))
status.setBackground(QtGui.QBrush(QtGui.QColor(255, 204, 204)))
font = QFont(results.status, weight=QFont.Bold)

But this was on the original QTableWidgetItem creation, and not from within the Thread, is there a way to achieve this?

Thanks in advance!
