Set font color on only one table row rather than entire document

Question

import docx
from docx.api import Document
from docx.shared import RGBColor
    
if condition:
    paragraph = row[2].add_paragraph('Different Text') # Not Blue
else:
    blue_paragraph = row[2].add_paragraph('X')
    font = blue_paragraph.style.font
    font.color.rgb = RGBColor(0x42, 0x24, 0xE9)

The above code is not only making my entire row[2] blue, it is making the entire document blue. How can I set only the 'X' text blue?

Answer 1

In this line:

font = blue_paragraph.style.font

You're selecting the font of what is probably the Normal style, and then setting it to blue in the following line. This explains why the whole document is turning blue; Normal is the default style for all paragraphs in the document.

You either need to create a new style that is blue and apply that to the paragraphs in question, or set the font of the runs of the target text directly.

So something like this would work, but be less optimal in some ways than using a style:

blue_paragraph = row[2].add_paragraph("X")
for run in blue_paragraph.runs:
    run.font.color.rgb = RGBColor(0x42, 0x24, 0xE9)
