Var n: integer;
procedure TForm1.Button1Click(Sender: TObject);
begin
  Shape3.Brush.Color:=ClMaroon;
  Shape4.Brush.Color:=ClOlive;
  Shape5.Brush.Color:=ClGreen;
  n:=n+1;
  if n>4 then n:=1;
  if n=1 then shape3.Brush.Color:=ClRed;
  if (n=2) or (n=4) then shape4.Brush.Color:=ClYellow;
  if n=3 then shape5.Brush.Color:=ClLime;
end;
