Use QWidget::palette to access widget's palette and QPalette::color to obtain the background color:

color = widget.palette().color(QPalette.Background)
print color.red(), color.green(), color.blue()

No, it's `.` in Python. – Pavel Strakhov Apr 15 '14 at 15:33

QPalette::Window - 10 - A general background color.

QPixmap::grabWindow(); can get you any part of the desktop.

Hope that helps.

import sys
from PyQt4 import QtGui, QtCore

class MainWin(QtGui.QDialog):
   def __init__(self,parent=None):
      QtGui.QDialog.__init__(self,parent)
      pal=QtGui.QPalette()
      role = QtGui.QPalette.Background
      pal.setColor(role, QtGui.QColor(0, 0, 255))
      self.setPalette(pal)

or with stylesheet

      self.setStyleSheet("background:blue)
