How to access font color of a text within a textbox using python-pptx?

I have not been able to find a straight forward answer to this, and it should be relatively simple:

Using python-pptx, I am trying to read the color of the font of the text inside a textbox on a slide.

I am not trying to change the color of the text but rather I am reading in a PowerPoint slide and I can access the text, shape, end points etc., but I also need to access the font color.

Currently I am trying:

for shape in slide.shapes:
    if shape.has_text_frame:
        text = shape.text_frame.text
        if shape.shape_type == 17:
            try:
                text_color = shape.text_frame.paragraphs[0].font.color.rgb
            except AttributeError:
                fill_color = None
        else:
            text_color = None

but its giving an Attribute Error: no .rgb property on color type '_NoneColor'

Solution

The font belongs to a run. So paragraphs[0].runs[0] should get you to the font object.
