Scoreboards teams multiple objectives (Nametags?)

Good day,

I'm currently working on my scoreboard add-on for a game, and i've encountered a problem.

Basically, i have this scoreboard which is for every client different (every client gets a different scoreboard object). The scoreboard displays coins and whatnot, and it works as it should.

I want to colour the persons' nametag to a certain colour by using the Team object which comes with
the Scoreboard API. I register the team on the scoreboard the player has, I just assign the player and the scoreboard coloring works. (using Team#setPrefix)

However, since the scoreboard is just for one client/player the coloured nametag / prefix / tab color is not viewable by other players, although I want that to happen.

TL;DR Give a person a seperate scoreboard but put them in global teams, so everyone can see the coloured nametags.

I need a push into the right direction, or a link of somesort.
My code is rather styled to my core, but i'll write it in pseudo of what I have.

Code:

Scoreboard board; //Image it being initialized
Player p; // ^

/* Some method */
Team team = board.registerNewTeam("etc");
team.setPrefix(ChatColor.GOLD.toString());

team.addPlayer(p);

p.setScoreboard(board);

/* Player p  can see his prefix, but other players cant.*/

I'm not stupid, I know multiple scoreboards cannot be assigned together, but I know some servers were able to colour nametags (globally for everyone viewable) while having content-unique scoreboards per-player.

I don't mind using packets (just link me xoxo)

Thanks!

 

Still no idea :/ Anyone?

Publicly viewable Nametags with personal scoreboards?
