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.
