code: def raw(self):
          
          self._ensure_mode(self.MODE_RGB_RAW)
          return self.value(0), self.value(1), self.value(2)
docs: Red, green, and blue components of the detected color, as a tuple.
          
          Officially in the range 0-1020 but the values returned will never be
          that high. We do not yet know why the values returned are low, but
          pointing the color sensor at a well lit sheet of white paper will return
          values in the 250-400 range.
  
          If this is an issue, check out the rgb() and calibrate_white() methods.
