We have automatic conversion between TBGRAPixel and TColor, that is not working fine?

Without the change in debugger mode it stops on:
function ColorToBGRA (color: TColor): TBGRAPixel;
in particular, it seems that a negative value is assigned to a cardinal.

ColorToBGRA call:
procedure RedGreenBlue(rgb: TColor; out Red, Green, Blue: Byte); inline;// does not work on system color

rgb: TColor = TGraphicsColor = -$7FFFFFFF-1..$7FFFFFFF;

procedure RedGreenBlue(rgb: TColor; out Red, Green, Blue: Byte);
begin
  (*if rgb < 0 then //if enabled it avoids debugger error (without the modification in the control code)
   Exit;*)
  Graphics.RedGreenBlue(rgb, Red, Green, Blue);
end; 

Graphics.RedGreenBlue() requires parameter
rgb: TColorRef = COLORREF = Cardinal (LCLType unit)
