As you can see here, the -1 is color white.

pawn Код:

format(str,sizeof(str),"[%02d:%02d:%02d] %s [%d]: %s",hours,minutes,seconds,PlayerName(playerid),playerid,text); 
        SendClientMessageToAll( -1, str); //

Therefore it will send the message in white, use GetPlayerColor, and put it instead of -1.
You can always show the rest of the message in white if you want it by putting {FFFFFF} in the string format, whereever you want it to be white.

So replace the above with this.

pawn Код:

format(str,sizeof(str),"[%02d:%02d:%02d] %s [%d]: {FFFFFF}%s",hours,minutes,seconds,PlayerName(playerid),playerid,text); 
        SendClientMessageToAll(GetPlayerColor, str);

Or ofcourse remove the {FFFFFF} if you do not want white color after the name. This works with other colors too, as long as you put them inside such boxes: { }
