vba - How to keep formats when I copy a range from Excel to outlook

Question

Hello i have an Excel table with some formats 10(Red) -> 15(Green), but at the end I loose all the formats i have in my excel. I use the next code to send and email from a range to outlook

Sub email()

    Dim OutApp As Object
    Dim OutMail As Object
    Dim Fname As String
    Dim hoja As String
    Dim rng As Range
    Dim celdas As String

    Set OutApp = CreateObject("Outlook.Application")
    Set OutMail = OutApp.CreateItem(0)

    Set rng = Range("C3:Q22")
    On Error Resume Next
    With OutMail

        .To = "juan"
        .CC = "Maria"
        .BCC = ""
        .Subject = "XXXX"
        .HTMLBody = "Hey" & RangetoHTML(rng)

        .Display   'or use .Display
    End With
    On Error GoTo 0

    'Kill Fname
    Set OutMail = Nothing
    Set OutApp = Nothing

End Sub

and the next function, I copied from the next link How to send mails from excel

Function RangetoHTML(rng As Range)
' Changed by Ron de Bruin 28-Oct-2006

    Dim fso As Object
    Dim ts As Object
    Dim TempFile As String
    Dim TempWB As Workbook

    TempFile = Environ$("temp") & "/" & Format(Now, "dd-mm-yy h-mm-ss") & ".htm"

    'Copy the range and create a new workbook to past the data in
    rng.Copy
    Set TempWB = Workbooks.Add(1)
    With TempWB.Sheets(1)
        .Cells(1).PasteSpecial Paste:=8
        .Cells(1).PasteSpecial xlPasteValues, , False, False
        .Cells(1).PasteSpecial xlPasteFormats, , False, False
        .Cells(1).Select
        Application.CutCopyMode = False
        On Error Resume Next
        .DrawingObjects.Visible = True
        .DrawingObjects.Delete
        On Error GoTo 0
    End With

    'Publish the sheet to a htm file
    With TempWB.PublishObjects.Add( _
         SourceType:=xlSourceRange, _
         Filename:=TempFile, _
         Sheet:=TempWB.Sheets(1).Name, _
         Source:=TempWB.Sheets(1).UsedRange.Address, _
         HtmlType:=xlHtmlStatic)
        .Publish (True)
    End With

    'Read all data from the htm file into RangetoHTML
    Set fso = CreateObject("Scripting.FileSystemObject")
    Set ts = fso.GetFile(TempFile).OpenAsTextStream(1, -2)
    RangetoHTML = ts.ReadAll
    ts.Close
    RangetoHTML = Replace(RangetoHTML, "align=center x:publishsource=", _
                          "align=left x:publishsource=")

    'Close TempWB
    TempWB.Close savechanges:=False

    'Delete the htm file we used in this function
    Kill TempFile

    Set ts = Nothing
    Set fso = Nothing
    Set TempWB = Nothing
End Function

While OP's accepted answer may have worked for him, I don't believe it's the right answer.

If you want to keep the formatting from your source you need to use xlPasteAllUsingSourceTheme

Code:

With TempWB.Sheets(1)
        .Cells(1).PasteSpecial Paste:=8
        '.Cells(1).PasteSpecial xlPasteValues, , False, False
        '.Cells(1).PasteSpecial xlPasteFormats, , False, False
        .Cells(1).PasteSpecial xlPasteAllUsingSourceTheme, , False, False
        .Cells(1).Select
        Application.CutCopyMode = False
        On Error Resume Next
        .DrawingObjects.Visible = True
        .DrawingObjects.Delete
        On Error GoTo 0
End With
