<p>I have a report that uses a TChart that I am maintaining.  One of the TLineSeries that gets added automatically gets assigned the color clWhite, which is too close to the background (clBtnFace).  </p>

<p>If I change it, then the next series that gets added takes clWhite.  So short of going back and changing it after all the other series are created, is there some way to tell the TChart that I don't want any of my series to be clWhite?</p>

<p>When a series is added to the TChart the TChart assigns it a color.  I want it to not assign clWhite.</p>

Near as I can tell from the TeeCharts module; no you can't specify a color that it should not be as it ships.
You can programatically walk through all the TLineSeries entries making sure at run-time that they don't use clWhite. 
Say you have an array of acceptable colors clArray, you can use the following code to set the colors of each of the tLineSeries entries at run time.
```
```
procedure TForm1.setColors(aChart: TChart; aColorArray: array of TColor);
var
  chi : Integer;
  coi : Integer;
begin
  coi := low(aColorArray);
  for chi := 0 to aChart.SeriesList.Count - 1 do begin
    aChart.SeriesList[chi].Color := aColorArray[coi];
    inc(coi);
    if coi > high(aColorArray) then
      coi := low(aColorArray);
  end;
end;

procedure TForm1.FormShow(Sender: TObject);
var
  ca : array of TColor;
begin
  setLength(ca, 3);
  ca[0] := clRed;
  ca[1] := clBlue;
  ca[2] := clGreen;
  setColors(Chart1, ca);
end;
```
