      Parses a specification of colors for a set of objects.
  
      Args:
          colors: A specification of colors for the objects. This can be one of the following:
              - None: to generate a color palette automatically.
              - A list of colors: where each color is either a string (specifying a named color) or an RGB tuple.
              - A string or an RGB tuple: to use the same color for all objects.
  
              If `colors` is a tuple, it should be a 3-tuple specifying the RGB values of the color.
              If `colors` is a list, it should have at least as many elements as the number of objects to color.
  
          num_objects (int): The number of objects to color.
  
      Returns:
          A list of 3-tuples, specifying the RGB values of the colors.
  
      Raises:
          ValueError: If the number of colors in the list is less than the number of objects to color.
                      If `colors` is not a list, tuple, string or None.
