Can I change the colour of player nameplates?

Solution 1:

I haven't played WoW for a long time, but when I played there used to be a ton of UI mods, which allowed you to configure the UI any way you wanted and I doubt that changed.

Curseforge is a great source for those addons.

WoW Interface is as well.

For your problem in particular one of those three might help:

Kuinameplates

Nephilistnameplates

nPlates

Solution 2:

I'd actually suggest Elvui, because you can adjust your complete interface with it and it has a great support.

In your particular case it could look like this:

You can enable or adjust:

• Class color
• Health bar
• Cast bar
• Character level
• and others

When you have it installed just type /ec and select NamePlates. There you can set the font face and size of several texts and other designs and select which ones you want to have customized (friendly players, enemy players, friendly npc, enemy npc, etc.) and even customize each of them separately (like displaying health bars, level, castbars,...).

PS: If you can't see them (regardless of the addon you're using) just press CTRL + V to toggle friendly nameplates.

Basic tutorial
