You can do this quite easily with this code:
Public Sub Demo() 'set color WorksheetName.Cells.Interior.ColorIndex = 1 'black 'clear color WorksheetName.Cells.Interior.ColorIndex = xlColorIndexNone end sub
Or, if you do not need VBA, just click on this little icon in the corner:

and select a color or do not use color - using the right-click menu or the ribbon menu.
Just because of the other answers, I want to remind you - there is no need to use a choice! This is a bad style macro recorder. There are only a few cases where the use of elections is necessary or a good idea. You can always use a specific range.
