Change paintEvent color with stylesheet?

Question

I'm trying to subclass a QCheckBox to inherit its behavior, but subclassing its paintEvent so that I can draw it like Android's toggle button. Is there a way to allow its stylesheet to determine the color it draws with?

In the example below I'm drawing an ellipse with a color I made as a qt Property in the hopes that I could do something like inst.setStyleSheet("MyCheckBox {MyColor: red;}") to make it red, but it does nothing. Is this possible?

from PySide2 import QtCore
from PySide2 import QtGui
from PySide2 import QtWidgets


class MyCheckBox(QtWidgets.QCheckBox):

    def __init__(self, parent=None):
        super(MyCheckBox, self).__init__(parent)

        self._myColor = QtGui.QColor(0, 255, 0)

    def myColor(self):
        return self._myColor

    def setMyColor(self, qcolor):
        self._myColor = qcolor

    MyColor = QtCore.Property(QtGui.QColor, myColor, setMyColor)

    def paintEvent(self, event):
        paint = QtGui.QPainter(self)
        paint.setBrush(self._myColor)
        paint.drawEllipse(0, 0, self.width(), self.height())

As the docs points out the syntax is qproperty-<property name>.

MyCheckBox {qproperty-MyColor: red;}
