How to find ALL the same values ​​in different sheets in Excel?

Question

Visual Basic

Many sheets in one dock. The first column is the same for everyone (for example, the name). I have a macro that highlights duplicate values ​​in a DIFFERENT color on the same sheet. I would like the others to also stand out in the SAME color as on the first one. How to implement?

Sub DuplicatesColoring()
     
    Dim Dupes()     'объявляем массив для хранения дубликатов
    ReDim Dupes(1 To Selection.Cells.Count, 1 To 2)
     
    Selection.Interior.ColorIndex = -4142   'убираем заливку если была
    i = 3
    For Each cell In Selection
        If WorksheetFunction.CountIf(Selection, cell.Value) > 1 Then
            For k = LBound(Dupes) To UBound(Dupes)
                'если ячейка уже есть в массиве дубликатов - заливаем
                If Dupes(k, 1) = cell Then cell.Interior.ColorIndex = Dupes(k, 2)
            Next k
            'если ячейка содержит дубликат, но еще не в массиве - добавляем ее в массив и заливаем
            If cell.Interior.ColorIndex = -4142 Then
                cell.Interior.ColorIndex = i
                Dupes(i, 1) = cell.Value
                Dupes(i, 2) = i
                i = i + 1
            End If
        End If
    Next cell
End Sub
