You don't need sscanf() for this params is already a string you only need to check if it's null. You should also work on your logic your using return; improperly it inflates your code uselessly.

CMD:me(playerid, params[])
{
    new string[128];
    if(isnull(params)) SendClientMessage(playerid, -1, "USAGE: /me [action]");
    else
    {
        new pName[MAX_PLAYER_NAME];
        GetPlayerName(playerid,pName,sizeof(pName));
        format(string, sizeof(string), "* %s %s",pName, action);
        SendClientMessage(playerid,COLOR_HERE,string); // <<----------
    }
    return 1;
}
