Answer 1

I would add a comment to Trilarions answer, but not enough rep..

I was able to use his suggestion, without removing borders by

self.show() 
self.button.setStyleSheet('background-color: red;')

AFTER doing a .show() on my application. not sure why after works but not before. If anyone can explain that would be great

Answer 2

For those who still want to change color of button with the instruction

button.setStyleSheet('QPushButton {background-color: #A3C1DA}')

and not able to do so, just modify the above instruction to

button.setStyleSheet('QPushButton {background-color: #A3C1DA; border:  none}')

And it will change the button color, so the trick is to remove the border

Answer 3

Apart from some inconsistencies with your code example setting the background color and text color of a QPushButton works just fine with:

setStyleSheet('QPushButton {background-color: #A3C1DA; color: red;}')

Example (using PySide):

from PySide import QtGui

app = QtGui.QApplication([])

button = QtGui.QPushButton()
button.setStyleSheet('QPushButton {background-color: #A3C1DA; color: red;}')
button.setText('Press Me')
menu = QtGui.QMenu()
menuItem1 = menu.addAction('Menu Item1')
menuItem2 = menu.addAction('Menu Item2')

button.setMenu(menu)
button.show()

app.exec_()

results in:
