IW15.2.10 TIWGrid cannot change font style/color using OnRenderCell

[defaultuser]

Hello, I'm using IW 15.2.10 And Delphi 10.3 trying to change the color of the font of text in cells within an IWGrid when OnRenderCell is triggered:

Code:

.
.
.
procedure WorkFlow.TasksRenderCell(ACell: TIWGridCell;
  const ARow, AColumn: Integer);
begin
  If ARow = 0 then
      exit;
{blue is the standard color for display only data}
    ACell.Font.Color := clBlue;
.
.
.

however, ACell.Font.Color := clBlue; line does not change of the color of the text in the cells. it does work on IW14, but this doesn't seem to work in IW15.2.10. could this be a bug?
