Change of Color in specific cells while exporting data from datagridview to Excel

Dear Coders,
 
With the help of Google and Our Coders I Managed to export the data in datagridview to Excel with the Column Headings. But now the thing is I would like to Highlight a specific cell with different colors in the exported data of Excel. Please Help. the code of the export data event is below.
 

Collapse | Copy Code
 
Dim ExcelApp As Object, ExcelBook As Object
Dim ExcelSheet As Object
Dim i As Integer
Dim j As Integer
 
'create object of excel
ExcelApp = CreateObject("Excel.Application")
ExcelBook = ExcelApp.WorkBooks.Add
ExcelSheet = ExcelBook.WorkSheets(1)
 
With ExcelSheet
    For i = 1 To Me.DataGridView1.ColumnCount
        .Cells(1, i) = DataGridView1.Columns(i - 1).HeaderText
    Next
    For i = 1 To Me.DataGridView1.RowCount
        For j = 0 To DataGridView1.Columns.Count - 1
            .cells(i + 1, j + 1) = DataGridView1.Rows(i - 1).Cells(j).Value
        Next
    Next
End With
