I have a ColorPalette with 500 assigned colors.

I want to iterate the colors and test for a match, if found I want to set SelectedIndex accordingly.

I tried rows and cols but same problem.

for i:= 0 to ColorPalette1.ColorCount-1 do begin
  if ColorPalette1.Color[i] = MyColor then begin
    ColorPalette1.SelectedIndex:= i;
    Break;
  end;
end;

Hi Andy

You can just use:

ColorPalette1.SelectedColor := MyColor;

Of course if the color is not in your list of 500 colors nothing will be selected.

In the coming update you can use:

ColorPalette1.SelectNearestColor( clBlue );
