Okay, so you have one function and it's sending you a 2 messages.
You need to do this:

pawn Код:

forward MessageToAdmins(color, const string[]);
public MessageToAdmins(color, const string[])
{
    for(new i = 0; i < MAX_PLAYERS; i++)
    {
        if(PlayerInfo[i][pAdminLevel] >=1)
        {
            //SendClientMessage(i, AdminColor, string);   - Delete this because you won't need it.
            SendClientMessage(i, Grey, string); // This function will send message in Grey color!
        }
    }
    return 1;
}

And now make another function...Something like this:

pawn Код:

forward MessageToAdminsFromAdmins(color, const string[]);
public MessageToAdminsFromAdmins(color, const string[])
{
    for(new i = 0; i < MAX_PLAYERS; i++)
    {
        if(PlayerInfo[i][pAdminLevel] >=1)
        {
            SendClientMessage(i, AdminColor, string);// And this function will send Message in AdminColor color!
            //SendClientMessage(i, Grey, string);    - Delete this because you won't need it.
        }                                       // Or leave it, I don't care...
    }
    return 1;
}

Change the colors you want, this was just an example.
Hope it helps.
