PowerShell EPPlus unable to change Backgroundcolor of Cells

I am creating an Excel Document using EPPlus. It is working, but I am not able to change the Background Color of Cells.
I use the following code for it:

Worksheet.Cells[row,column].Style.Fill.BackgroundColor.rgb = (255,0,0)


Everytime I execute the script it says:

"rgb" is a read-only property

When I try to set the

Worksheet.Cells.Style.Fill.BackgroundColor = xxx


I get the same error:

"BackgroundColor" is a read-only property

I did not find more options, where you might change the Color or change the property to writeable...
Does anyone have an idea?

Try my PowerShell Excel module that wraps EPPlus and makes interaction really easy.

$xlfile = "$env:TEMPtest.xlsx"
rm $xlfile -ErrorAction Ignore

$pkg = ps | select company, Handles| Export-Excel $xlfile -PassThru

$ws = $pkg.Workbook.Worksheets["Sheet1"]

Set-Format -WorkSheet $ws -Range "B2:B2" -BackgroundColor Red
Set-Format -WorkSheet $ws -Range "B5:B5" -BackgroundColor Green

Close-ExcelPackage $pkg -Show


You set the color like this.

Worksheet.Cells[row,column].Style.Fill.PatternType = ExcelFillStyle.Solid;
Worksheet.Cells[row,column].Style.Fill.BackgroundColor.SetColor(Color.Red);
