GuildList player name color

[Antiklesys]

Is there any way to change to color of a specific player in the GuildList frame in Classic?
Wow already does it automatically for "online" and "offline" players but what if I want to change the color or "highlight" the names of certain players?
E.g. I want to color in "red" the names of all my officers regardless of their online or offline status?
Or even change the color of a specific person, whatever is simpler to showcase with a code example.
I've been trying to find some resources about that but failed, anyone can point me in the right direction?
