Conditional formatting help needed

Hi, Im new to this forum and rusty with Excel, but hope you can help.

I have a simple spreadsheet to record tasks in a log format. I have a date column A3 that shows the date a job is logged. I have a 'completed' column I3 that is blank until the completion date is entered. I want to be able to 'fill' the blank cells in the I3 column with colours representing the number of days after the date in column A3 as follows:

The default fill for an empty cell I3 should be light green/black text
If still blank 3 days after the date in A3, column I3 should change to orange.
If still blank 5+ days after the date in A3, colum I3 should change to red.
If a date is entered into I3 then the fill should return to the default (light green/black text).

The above will give a visual representation of jobs slightly or seriously overdue.

Hopefully the above makes sense however try as I have for two days I cannot get this to work.

Thanks in anticipation.

Maybe

Formula:

=AND(I3="", TODAY()-A3>=3)

format orange
And

Formula:

=AND(I3="", TODAY()-A3>=5)

format red

Welcome to the forum

Please attach a sample workbook (not a picture or pasted copy). Make sure there is just enough data to demonstrate your need. Include a BEFORE sheet and an AFTER sheet in the workbook if needed to show the process you're trying to complete or automate. Make sure your desired results are shown, mock them up manually if necessary.

Remember to desensitize the data.

Click on GO ADVANCED and then scroll down to Manage Attachments to open the upload window.

If the default, blank, is the same as when there is a date, you don't need CF ... just set the default colour for the range using cell format fill colour.

CF formulas
For Red
=AND($I3="",TODAY()>=$A3+7)

For Orange
=AND($I3="",TODAY()>=$A3+3,TODAY()<$A3+7)

For Green
=AND($I3="",TODAY()>=$A3,TODAY()<$A3+3)

For Grey and text black
=$I3<>""
