You can use this, http://www.colorpicker.com/. I always use it for colours, remember to do {colour code here}!

Also, I found a little mistake with your code.

pawn Код:

if(strcmp(cmdtext, "/staff", true) == 0)
    {
        ShowPlayerDialog(playerid, 9, DIALOG_STYLE_MSGBOX, "STAFF-MEMBERS", "/-MEMBERS-/\n[OWNERS]=> [GTA]Leon,[GTA]Badboy \n{FFFFFF}[HEAD-ADMINS]=> [GTA]Lambi, [GTA]DeadMan \n{FFFFFF}[ADMINS]-, ?\n{FFFFFF}[V.I.P]-, \n{FFFFFF}[MODERATORS]-:)\n", "Ok", "Close");
        GameTextForAll("~r~/STAFF", 6000, 5);
        return 1;
        }
