Conditional formatting due date

[Klock1995]

I am trying to add a conditional format to automatically change text color from black to red if item is not checked in AND the due date has passed.

Could you attach a small sample workbook demonstrating the problem (without sensitive data), or if that is not possible, make it available through OneDrive, Google Drive, Dropbox or similar?
