Colour codes like "{FF0000}" are hidden in the chat text input. You need to replace the format of the code into some others, and convert them back when you use SendClientMessage(ToAll).

Also,

pawn Код:

format(string, sizeof(string), "(%d): %s", playerid, text);//Putting [0] will only output the first character of the text.
SendPlayerMessageToAll(GetPlayerColor(playerid), string);//You need to use SetPlayerColor in OnPlayerConnect first if you want to use this, otherwise you need to change GetPlayerColor(playerid) into some other constant colours.
