PX color_scale_continous docs incomplete

Here https://github.com/plotly/plotly.py/blob/master/packages/python/plotly/plotly/express/_doc.py#L164

We accept color scale names also right?

Yeah, px is using the same colorscale validator as graph objects now. Here's where that docstring is generated:

plotly.py/packages/python/plotly/_plotly_utils/basevalidators.py

Lines 1550 to 1562 in 168398e

	desc = """\
	The '{plotly_name}' property is a colorscale and may be
	specified as:
	- A list of colors that will be spaced evenly to create the colorscale.
	Many predefined colorscale lists are included in the sequential, diverging,
	and cyclical modules in the plotly.colors package.
	- A list of 2-element lists where the first element is the
	normalized color level value (starting at 0 and ending at 1),
	and the second item is a valid color string.
	(e.g. [[0, 'green'], [0.5, 'red'], [1.0, 'rgb(0, 0, 255)']])
	- One of the following named colorscales:
	{colorscales_str}
	""".format(

So it would probably make sense to combine the generation of these docstrings into a common function in _plotly_utils.
