PDF checkbox color not working

Question

Hi,

I am trying to change the default checkbox tick colour in a downloading PDF file but the tick colour is always black. Any thought please?

Please refer to my code snippet below

loadedDocument.Form.Fields.TryGetField(field, out PdfLoadedField loadedField);

var sf = loadedField as PdfLoadedCheckBoxField;

sf.ForeColor = new PdfColor(Color.Blue);

sf.BorderColor = new PdfColor(Color.Blue);

sf.BackColor = new PdfColor(Color.Blue);

sf.Checked = true;

//Get the loaded form. 
PdfLoadedForm loadedForm = loadedDocument.Form; 
 
loadedForm.SetDefaultAppearance(false); 
//load the check box from field collection 
 
PdfLoadedCheckBoxField loadedCheckBoxField = loadedForm.Fields[0] as PdfLoadedCheckBoxField; 
 
// fill the checkbox forecolor 
loadedCheckBoxField.ForeColor = new PdfColor(Color.Blue); 
 
//load the check box from field collection 
PdfLoadedCheckBoxField loadedCheckBoxField1 = loadedForm.Fields[1] as PdfLoadedCheckBoxField;

loadedCheckBoxField1.ForeColor = new PdfColor(Color.Red);
