Hello, Jesse,

Thank you for bringing this to our attention. The possible solution that I can suggest is to specify Black color for the column/row headers in the form's Load event:

        protected override void OnLoad(EventArgs e)
            Telerik.WinForms.Controls.Spreadsheet.Worksheets.RadWorksheetEditor activeEditor = this.radSpreadsheet1.SpreadsheetElement.ActiveSheetEditor as RadWorksheetEditor;
            foreach (var c in activeEditor.Children)
                Telerik.WinControls.Spreadsheet.UI.Panel p = c as Telerik.WinControls.Spreadsheet.UI.Panel;
                if (p != null)
                    p.BackColor = Color.Black;

I hope this helps.
