How To Get Actual Color Of Text In MS Word When Python-docx Returns None

I'm not 100% certain that this would work, but theoretically it should solve the issue you're facing. From the python-docx documentation:

1. The CharacterStyle class has attributes base_style and font.
2. Since the base_style object points to another CharacterStyle instance (or None), you can make a "nested" query until you find a font color.

style = run.stylewhile style:    if style.font.color.rgb:        color = style.font.color.rgb        break    else:        style = style.base_style
