How to individually customize QTabWidget tabs? - pyqt5

Question

A MRE to customize QTabWidget tabs reads:
import sys
from PyQt5.QtWidgets import QMainWindow, QApplication, QLabel, QWidget, QAction, QTabWidget,QVBoxLayout
from PyQt5.QtCore import pyqtSlot
class App(QMainWindow):
def __init__(self):
super().__init__()
self.title = 'Tabs tailoring'
self.setWindowTitle(self.title)
self.table_widget = TailoredWidget(self)
self.setCentralWidget(self.table_widget)
self.show()
class TailoredWidget(QWidget):
def __init__(self, parent):
super(QWidget, self).__init__(parent)
self.layout = QVBoxLayout(self)
# Initialize tab screen
self.tabs = QTabWidget()
self.tabs.setStyleSheet('''QTabBar::tab {font-size: 20pt; color: #00004F; height: 40px; width: 140px;}''')
self.tab1 = QWidget()
self.tab2 = QWidget()
self.tab3 = QWidget()
# Add tabs
self.tabs.addTab(self.tab1,"TAB 1")
self.tabs.addTab(self.tab2,"TAB 2")
self.tabs.addTab(self.tab3,"TAB 3")
# Add tabs to widget
self.layout.addWidget(self.tabs)
self.setLayout(self.layout)
#pyqtSlot()
def on_click(self):
print("\n")
for currentQTableWidgetItem in self.tableWidget.selectedItems():
print(currentQTableWidgetItem.row(), currentQTableWidgetItem.column(), currentQTableWidgetItem.text())
if __name__ == '__main__':
app = QApplication(sys.argv)
ex = App()
sys.exit(app.exec_())
This works as expected and allows to play around with the setStyleSheet parameters. However, I'd prefer to be able to customize each tab individually. I tried modifying the initialization of the tabs to:
# Initialize tab screen
self.tabs = QTabWidget()
# self.tabs.setStyleSheet('''QTabBar::tab {font-size: 30pt; color: #00004F; height: 40px; width: 140px;}''')
self.tab1 = QWidget()
self.tab1.setStyleSheet('''QTabBar::tab {font-size: 15pt; color: #55004F; height: 40px; width: 140px;}''')
self.tab2 = QWidget()
self.tab2.setStyleSheet('''QTabBar::tab {font-size: 20pt; color: #AA004F; height: 40px; width: 140px;}''')
self.tab3 = QWidget()
self.tab3.setStyleSheet('''QTabBar::tab {font-size: 25pt; color: #FF004F; height: 40px; width: 140px;}''')
but this doesn't do anything. Is there any way to assign each tab different properties?
