you can make it like this

PHP код:

CMD:asay(playerid, params[])
{
 new text[128],string[128], tmp2[33];
 if(sscanf(params, "ss[128]", tmp2, text)) return SendClientMessage(playerid,-1, "Use: /asay [color] [message]");
 if(strlen(tmp2) < 3 || strlen(tmp2) > 30) return SendClientMessage(playerid, COLOR_RED, "Error: The color should be between 3 and 30 characters.");
 format(string, sizeof(string),"Admin %s: {%s}%s", Name(playerid), tmp2, text);
 SendClientMessageToAll(-1,string);
 return 1;
} 


00FF00 = Light Green
008800 = Dark Green
FF0000 = Red
CBCBCB = Grey
