How to Change Excel Cell Color Dynamically using C#

Question

Using the below link, I am able to loop through the rows and able to get exact cell, but unable to set its color. Please see the code below.

How do I dynamically set the forecolour of my column data based on the value when exporting excel using EPPLUS?

var costStructureReport = new
            {
                CurrentQuotation = rptCostStructure.GetCostStructureReport()
            };

 var reportEngine = new ReportEngine();
            string fileName = reportEngine.ProcessReport(ReportNames.ProjectDownload_Template, reportname + ".xlsx", costStructureReport);

            var ep = new ExcelPackage(new FileInfo(fileName));
            var sheet1 = ep.Workbook.Worksheets["SPR_ProjectDownload"];
            var row = sheet1.Dimension.End.Row;
            
            for(int i=0;i< costStructureReport.CurrentQuotation.Count;i++)
            {
                if (costStructureReport.CurrentQuotation[i].MaterialCost_ByUser)
                {
                    sheet1.Cells[i+2, 2].Style.Font.Color.SetColor(System.Drawing.Color.Red);
                    sheet1.Cells[i + 2, 12].Style.Font.Color.SetColor(System.Drawing.Color.Red);
                    sheet1.Cells[i + 2, 12].Style.Font.Bold = true;
                }

            }

You can Change the Text Color using

[RangeObject].Font.Color = System.Drawing.ColorTranslator.ToOle(System.Drawing.Color.Red);

And Font Colour using

[RangeObject].Interior.Color =System.Drawing.ColorTranslator.ToOle(System.Drawing.Color.Red);
