[Python] How can I change the color for selected (highlighted) items in a QListWidget (Qt,...

I'm trying to make a QListWidget subclass that will have just a cyan border when an item is selected

But when I use transparent in its stylesheet I get a gray-like color (in fusion style) and when I go with normal style I get a whole white color

I just want to have a cyan border with the existing background color

Here's my code:

import sys
from PySide6.QtWidgets import (
QApplication, QMainWindow, QWidget, QVBoxLayout,
QListWidget, QListWidgetItem)
from PySide6.QtCore import Qt
from PySide6.QtGui import QFont
from PySide6.QtWidgets import QApplication
from PySide6.QtGui import QFont, QColor

class NewListWidget(QListWidget):
def __init__(self, *args, **kwargs):
super().__init__(*args, **kwargs)
self.setStyleSheet("""
QListWidget::item:selected {
background-color: transparent;
border: 2px solid #00AEEF;
}
""")
# Other things

class MainWindow(QMainWindow):
def __init__(self):
super().__init__()
self.setWindowTitle('Study Planner')
self.resize(210,210)

central = QWidget()
self.setCentralWidget(central)
layout = QVBoxLayout(central)

self.item_list = NewListWidget()
self.item_list.setFixedHeight(200)
sample_items = {
'item1': ["#8f0000"],
'item2':["#000073"],
'item3':["#166300"],
}

for item_name,data in sample_items.items():
a = QListWidgetItem(item_name)
a.setTextAlignment(Qt.AlignCenter)
a.setForeground(QColor("#FFFFFF"))
a.setBackground(QColor(data[0]))
self.item_list.addItem(a)

self.item_list.setFont(QFont("Times new roman",14))
self.item_list.setFixedWidth(200)

layout.addWidget(self.item_list)
if __name__ == '__main__':
app = QApplication(sys.argv)
app.setStyle('fusion')

win = MainWindow()
win.show()
sys.exit(app.exec())



This is what I get (fusion style):

unselected :

selected :

Also in normal style:

unselected:

selected:
