Funny this example works as expected:

from PyQt4.QtCore import *
from PyQt4.QtGui import *

class AllGreen(QWidget):
     def __init__(self):
         QWidget.__init__(self)
         layout = QVBoxLayout(self)

         self.w1 = QLineEdit(self)
         self.w2 = QLineEdit(self)
         self.w3 = QLineEdit(self)

         palette = self.palette()
         role = self.backgroundRole()
         palette.setColor(role, QColor('green'))
         self.setPalette(palette)

         palette1 = self.w1.palette()
         role = self.w1.backgroundRole()
         palette1.setColor(role, QColor('red'))
         self.w1.setPalette(palette1)

         palette2 = self.w2.palette()
         role = self.w2.backgroundRole()
         palette2.setColor(role, QColor('yellow'))
         self.w2.setPalette(palette2)

         palette3 = self.w3.palette()
         role = self.w3.backgroundRole()
         palette3.setColor(role, QColor('red'))
         self.w3.setPalette(palette3)
         layout.addWidget(self.w1)
         layout.addWidget(self.w2)
         layout.addWidget(self.w3)

def testWidget():
     import sys
     a = QApplication(sys.argv)
     QObject.connect(a,SIGNAL("lastWindowClosed()"),a,SLOT("quit()"))

     w = AllGreen()
     w.show()
     a.exec_()

if __name__ == "__main__":
     testWidget()
