How do I restore Cell Background Color in VB Script while using Excel

I am supporting with some seniors on voluntary basis for a non profit organization.
Some of them have difficulty to identify the active cell . So I followed the instruction as per YouTube

 [https:]//[youtu.be/VJczGRH-4Ro]  Sorry I am unable to post link so i have added brackets.

The important script I am using is

Private Sub Workbook_SheetSelectionChange(ByVal Sh As Object, ByVal Target As Range)
Cells.Interior.ColorIndex = xlColorIndexNone
Target.EntireColumn.Interior.ColorIndex = 8
Target.EntireRow.Interior.ColorIndex = 8
Target.Interior.ColorIndex = 7
End Sub

This works perfectly fine for highlighting the active cell. Basically it will highlight active row, active column and active cell background in different color.
Unfortunately while moving from one cell to another cell, the background color of active row, column and cell is reset to normal.
How do I restore the background color?

So basically If my understanding is correct before entering the cell, I need to store the current background of row, column and cell in a variable. while leaving I should restore back.
I am not sure how do I read? what function I should store? what function I should restore?
Since I am new to VB Script, request your help.

Thank you
