Name tag colors

[Mystdee]

I have searched for the answer to this question, but didn't find it. If it's been discussed before I am sorry to repeat. . . . .

I am still a relative newbie in POTCO (about 3 weeks lvl 22) and I have been wondering what the different colored names on the players in the game signify. some are grey some blue and some gold - maybe others but those seem the most common, I thought it was a level or guild thing but have seen some that are same level and/or guild that are not the same colors. So I just thought I'd ask out of sheer curiosity!
