BackColor Bug

[Thaledwyn]

I used your Hello World example to play around with the BackColor feature.

When I do the following:

    Dim sheet = New Worksheet("Hello, world!")
    sheet.Cells(0, 0) = "Hello,"
    sheet.Cells("B1") = "World!"
    sheet.Cells(0, 0).Fill.BackgroundColor = Color.Blue
    sheet.Cells("B1").Fill.BackgroundColor = Color.Red
    Dim workbook = New Workbook()
    workbook.Add(sheet)
    workbook.Save(Application.StartupPath & "\test.xlsx")

both cells have a blue backcolor.

When I first create two cells, add format and assign them to the sheet, I get the same behaviour.

What is wrong?
I'm using VS2013 with target framework 4.5.

Will check, that code looks good at first glance, but Excel does some weird stuff with the background/foreground colors at times.

There was indeed a bug in Simplexcel, Version 2.2.1.71 should fix that. Thank you for the report!
