How do you change character name color?

[Thorazine]

I know you can change title colors but I see people with different colored character names, how is that done?

[Trickshooter]

They've just selected "Help me!" or "Helper" after creating a character. Changes your name either Yellow or Purple, but I forget which is which.

Thank you!

Help Me is purple, Helper yellow. 

 

You can change the color of your titles when you level far enough to get one.  For some reason they default to solid black.
