Make sure you are using:

using Excel = Microsoft.Office.Interop.Excel;

If you have a variable for the range you want to change, then use:

chartRange = xlWorkSheet.get_Range("a5", "a8");    
chartRange.Interior.Color = System.Drawing.ColorTranslator.ToOle(System.Drawing.Color.Black);

If you want to just change the color of a specific cell, then use:

xlWorkSheet.Cells[row, col].Interior.Color = System.Drawing.ColorTranslator.ToOle(System.Drawing.Color.Black);

...where 'row' is the row number, and 'col' is the column number assigned to the given lettered columns (starting at 1).
