How to change worksheet color based on its condition

Dear Experts,
I'm truly beginner on spreadsheet, I want to make conditions on sheets, the worksheet background color should turns to red if the data on the sheet is uncompleted. If the data on the sheet is completed, the worksheet background color should turns to green.

I attach the example files regarding to my question.
Any responds from you would be appreciated.

Regards,
Saesaria
