Цветной текст в PyQt5

Question

Как мне вывести цветной текст в menu_bar?

Пробовал через Colorama - ничего не получилось.

from PyQt5.QtWidgets import QMainWindow, QTextEdit, QMenuBar, QApplication
from PyQt5.QtCore import QObject
from PyQt5.QtCore import pyqtSignal as Signal
  
  
class OutputLogger(QObject):
    emit_write = Signal(str, int)
  
    class Severity:
        DEBUG = 0
        ERROR = 1
  
    def __init__(self, io_stream, severity):
        super().__init__()
         self.io_stream = io_stream
        self.severity = severity
  
    def write(self, text):
        self.io_stream.write(text)
        self.emit_write.emit(text, self.severity)
  
    def flush(self):
        self.io_stream.flush()
  
  
import sys
OUTPUT_LOGGER_STDOUT = OutputLogger(sys.stdout, OutputLogger.Severity.DEBUG)
OUTPUT_LOGGER_STDERR = OutputLogger(sys.stderr, OutputLogger.Severity.ERROR)
  
sys.stdout = OUTPUT_LOGGER_STDOUT
sys.stderr = OUTPUT_LOGGER_STDERR
  
  
class MainWindow(QMainWindow):
    def __init__(self):
        super().__init__()
        self.text_edit = QTextEdit()
  
        OUTPUT_LOGGER_STDOUT.emit_write.connect(self.append_log)
        OUTPUT_LOGGER_STDERR.emit_write.connect(self.append_log)
  
        menu_bar = QMenuBar()
        menu = menu_bar.addMenu('Say')
        menu.addAction('hello', lambda: print('Hello!'))
        menu.addAction('fail', lambda: print('Fail!', file=sys.stderr))
        self.setMenuBar(menu_bar)
  
        self.setCentralWidget(self.text_edit)
  
    def append_log(self, text, severity):
        text = repr(text)
        if severity == OutputLogger.Severity.ERROR:
            self.text_edit.append('<b>{}</b>'.format(text))
        else:
            self.text_edit.append(text)
  
  
if __name__ == '__main__':
    app = QApplication([])
    mw = MainWindow()
    mw.show()
    print('Go!')
    app.exec()
