docstr: Construct a new Colorscale object
  
  Parameters
  ----------
  arg
      dict of properties compatible with this constructor or
      an instance of
      :class:`plotly.graph_objs.layout.Colorscale`
  diverging
      Sets the default diverging colorscale. Note that
      `autocolorscale` must be true for this attribute to
      work.
  sequential
      Sets the default sequential colorscale for positive
      values. Note that `autocolorscale` must be true for
      this attribute to work.
  sequentialminus
      Sets the default sequential colorscale for negative
      values. Note that `autocolorscale` must be true for
      this attribute to work.
  
  Returns
  -------
  Colorscale
