        -- The function SHOULD return a Vector with the chosen player's colour.

        -- In sandbox this function is created as a network function, 
        -- in player_sandbox.lua in SetupDataTables

```
Proxies {
    PlayerColor {
       resultVar $color2
       myVariable $color
    }
}
```

values = {
    resultvar = "$color2"
    myvariable = "$color"
}
