How to set comment/note background color

hi, i think it should be simple but i cannot find the method.
after adding a new note into cell… the background color of the note is ‘white’.
However, in excel, the background color of the note is yellow.
How can I set the background color of the note same as the excel background color?

Example code as following…
var sourceSheet = _workbook.Worksheets[sheetName];
var commentIndex = sourceSheet.Comments.Add(cellAddress);
var comment = sourceSheet.Comments[commentIndex];
comment.Note = note;

@catalparue26,

Thanks for the code segment and details.

See the following sample code on how to set comment/note formatting/color (especially second comment) for your reference, you may change the code accordingly:
e.g
Sample code:

//Instantiate the Workbook
            Workbook workbook = new Workbook();
            //Get a reference of comments collection with the first sheet
            CommentCollection comments = workbook.Worksheets[0].Comments;
            //Add a comment to cell A1
            int commentIndex = comments.Add(0, 0);
            Comment comment = comments[commentIndex];
            comment.Note = "First note.";
            comment.Font.Name = "Times New Roman";
            //Load an image into stream
            Bitmap bmp = new Bitmap("e:\\test\\school.jpg");
            MemoryStream ms = new MemoryStream();
            bmp.Save(ms, System.Drawing.Imaging.ImageFormat.Png);
            //Set image data to the shape associated with the comment
            comment.CommentShape.FillFormat.ImageData = ms.ToArray();

            commentIndex = comments.Add(2, 1);
            Comment comment2 = comments[commentIndex];
            comment2.Note = "Second note.";
            LineFormat lineFormat = comment2.CommentShape.Line;
            lineFormat.SolidFill.Color = Color.Red;
            FillFormat fillFormat = comment2.CommentShape.Fill;
            fillFormat.SolidFill.Color = Color.Pink;//you may change the color
            
            
            //Save the workbook
            workbook.Save("e:\\test2\\out2_comments_formatting.xlsx"); 

Hope, this helps a bit.
