How to color TPanels on a form according to their Tag properties

Answer:

1   { ... }
2   var
3     ix: Integer;
4     pnl: TPanel;
5     { ... }
6   
7     for ix := 0 to ComponentCount - 1 do
8     begin
9       if Components[ix] is TPanel then
10      begin
11        pnl := TPanel(Components[ix]);
12        case pnl.Tag of
13          1: pnl.Color := clRed;
14          2: pnl.Color := clBlue;
15        else
16          pnl.Color := clBtnFace;
17        end;
18      end;
19    end;


Try placing the above code in a button OnClick event handler (having dropped some TPanels on the form with different Tag values).
