          Apply a pygments color scheme to the console.
  
          As there is not a 1 to 1 mapping between color scheme formats and
          console formats, we decided to make the following mapping (it usually
          looks good for most of the available pygments styles):
  
              - stdout_color = normal color
              - stderr_color = red (lighter if background is dark)
              - stdin_color = numbers color
              - app_msg_color = string color
              - bacgorund_color = background
  
  
          :param color_scheme: pyqode.core.api.ColorScheme to apply
          """
          self.stdout_color = color_scheme.formats['normal'].foreground().color()
          self.stdin_color = color_scheme.formats['number'].foreground().color()
          self.app_msg_color = color_scheme.formats[
              'string'].foreground().color()
          self.background_color = color_scheme.background
          if self.background_color.lightness() < 128:
              self.stderr_color = QColor('#FF8080')
          else:
              self.stderr_color = QColor('red')
