code: def lab2rgb(lab, illuminant="D65", observer="2"):
      """Lab to RGB color space conversion.
      Parameters
      ----------
      lab : array_like
          The image in Lab format, in a 3-D array of shape ``(.., .., 3)``.
      illuminant : {"A", "D50", "D55", "D65", "D75", "E"}, optional
          The name of the illuminant (the function is NOT case sensitive).
      observer : {"2", "10"}, optional
          The aperture angle of the observer.
      Returns
      -------
      out : ndarray
          The image in RGB format, in a 3-D array of shape ``(.., .., 3)``.
      Raises
      ------
      ValueError
          If `lab` is not a 3-D array of shape ``(.., .., 3)``.

      x_ref=95.047, y_ref=100., z_ref=108.883. See function `get_xyz_coords` for
      a list of supported illuminants.
