I specifically asked staff via email sometime in the past 2-3 years (more recently than that forum thread) if it was okay to implement category-reddening code wiki-wide in the CSS and I was told it was fine and if they ever decided it wasn't then I wouldn't get in trouble for adding it since they said it was okay.

This can be seen in one of my responses to this thread I made before I sent an email.
