Bagaimana cara menambahkan warna pada kolom excel tertentu berdasarkan kondisi menggunakan openxml?

Saya membuat lembar excel dan saya ingin mewarnai kolom excel berdasarkan kondisi. Sekarang semua kolom excel saya mendapat warna merah. Saya hanya ingin mewarnai nama kolom tertentu.

Saya menggunakan XML terbuka untuk menghasilkan excel, apakah ada cara untuk menemukan sel untuk menerapkan warna

 using (SpreadsheetDocument document = SpreadsheetDocument.Create(path, SpreadsheetDocumentType.Workbook))
            {
                WorkbookPart workbookPart = document.AddWorkbookPart();
                workbookPart.Workbook = new Workbook();

                WorksheetPart worksheetPart = workbookPart.AddNewPart<WorksheetPart>();
                worksheetPart.Worksheet = new Worksheet();

                Sheets sheets = workbookPart.Workbook.AppendChild(new Sheets());

                Sheet sheet = new Sheet() { Id = workbookPart.GetIdOfPart(worksheetPart), SheetId = 1, Name = "Template" };

                sheets.Append(sheet);

                var stylesheet = new Stylesheet() { MCAttributes = new MarkupCompatibilityAttributes() { Ignorable = "x14ac" } };
                stylesheet.AddNamespaceDeclaration("mc", "http: //schemas.openxmlformats.org/markup-compatibility/2006");
                stylesheet.AddNamespaceDeclaration("x14ac", "http: //schemas.microsoft.com/office/spreadsheetml/2009/9/ac");

                var fills = new Fills() { Count = 5U };
                var fonts = new Fonts() { Count = 1U, KnownFonts = true };
               // var cellFormats = new CellFormats();
                Font font = new Font();
                font.Append(new Color() { Rgb = "ff0000" });
                fonts.Append(font);

               // cellFormats.AppendChild(new CellFormat() { FontId = 0U });
                stylesheet.Append(fonts);
                stylesheet.Append(fills);
                //stylesheet.Append(cellFormats);
                //stylesheet.Append(fill);                 
                var stylePart = workbookPart.AddNewPart<WorkbookStylesPart>();
                stylePart.Stylesheet = stylesheet;
                stylePart.Stylesheet.Save();

                workbookPart.Workbook.Save();

                SheetData sheetData = worksheetPart.Worksheet.AppendChild(new SheetData());

                // Constructing header
                Row row = new Row();

                foreach (DataExchangeDefinition a in importColList)
                {
                    defnExist = true;
                    if (a.MustFieldYN == true)
                    {
                        row.Append(
                        ConstructCell(a.FieldCaption, CellValues.String));
                    }
                    else
                    {
                        row.Append(
                        ConstructCell(a.FieldCaption, CellValues.String));
                    }
                }

                if (defnExist == false)
                {
                    row.Append(
                    ConstructCell("Excel Template Definition Missing", CellValues.String));
                }
                // Insert the header row to the Sheet Data
                sheetData.AppendChild(row);

                // Inserting each employee

                worksheetPart.Worksheet.Save();
            }

Berikut adalah metode membangun sel

 private Cell ConstructCell(string value, CellValues dataType)
    {
        Cell c = new Cell()
        {
            CellValue = new CellValue(value),
            DataType = new EnumValue<CellValues>(dataType)
            //StyleIndex=0U                
        };
        return c;
    }

Apakah ada cara untuk mengatasi ini?
