To set the font color and size, you can use the QFont object and QPalette object.

Firstly, create a QFont object and set the font size using the setPointSize() method.

font = QtGui.QFont()
font.setPointSize(12)

Next, create a QPalette object and use the setColor() method to set the font color.

palette = QtGui.QPalette()
palette.setColor(QtGui.QPalette.Text, QtCore.Qt.red)

Finally, apply the QFont object and QPalette object to the widget.

widget.setFont(font)
widget.setPalette(palette)

The complete sample code is shown below.

from PyQt5 import QtWidgets, QtGui, QtCore

app = QtWidgets.QApplication([])

widget = QtWidgets.QWidget()

font = QtGui.QFont()
font.setPointSize(12)

palette = QtGui.QPalette()
palette.setColor(QtGui.QPalette.Text, QtCore.Qt.red)

widget.setFont(font)
widget.setPalette(palette)

widget.show()

app.exec()

The code above sets the font size of the control to 12 and the color to red. You can modify the font size and color as needed.
