There is no event triggered on format change.

The best workaround is to monitor the Worksheet_SelectionChange event. When the user clicks a cell, you have to store a reference to the cell, and all the format information you want to monitor for. Next time the event fires, you have to look back at the last cell they clicked, compare it's current format to your saved format information, and that will allow you to detect changes.

The downside is you can only detect the change after they have clicked away from the cell they formatted.

Private Sub Worksheet_SelectionChange(ByVal Target As Range)
    Static LastRange As Range 'The last range selected'
    'For example, monitor the background color or the cell'
    Static LastColorIndex As Integer

    If LastRange.Cells(1).Interior.ColorIndex <> LastColorIndex Then
        'Do what you do'
    End If

    Set LastRange = Target
    LastColorIndex = Target.Interior.ColorIndex
End Sub

This is the simplest possible case. Things get more complicated if they modify an entire range of cells at once.
