Adding BackColor Macro to all Checkboxes in an Excel Worksheet

I have an Excel worksheet with a large number of checkboxes. To improve visual clarity, I want the BackColor property of a given checkbox to change when it is checked (and revert back to white when unchecked). This should apply to each checkbox.

Here's my (very basic) macro to achieve this for an individual checkbox:

Private Sub CheckBox1_Click()
    If CheckBox1.Value = True Then
      CheckBox1.BackColor = RGB(255, 0, 0)
    ElseIf CheckBox1.Value = False Then
        CheckBox1.BackColor = RGB(255, 255, 255)
    End If
End Sub

But I cannot get it to work for all checkboxes without painstakingly adding this macro for each individual checkbox. Any help is greatly appreciated (and sorry if this is a very basic question, I'm fairly new to vba)!
