Move and copy the next destinated column and copy if the main target column is empty

[TheLSD]

Sub Macro2()
    Dim ws As Worksheet, MasterSheet As Worksheet
    Dim originalDestinationCell As Range, nextDestCell As Range
    Dim firstGreyCell As Range, rangeToSearchIn As Range, c As Range

    Set MasterSheet = Sheets("Sheet1")            'where you want to put the copied data
    Set originalDestinationCell = MasterSheet.Range("C6") 'the first cell the data will be copied to
    Set nextDestCell = originalDestinationCell.Offset(-1, 0)
    
    For Each ws In ThisWorkbook.Worksheets
        If Not ws.Name = MasterSheet.Name Then
            Set firstGreyCell = ws.Range("C6")
            Set rangeToSearchIn = ws.Range("C6:C1500") 'the range that the data is in
            
            For Each c In rangeToSearchIn
                If IsEmpty(c) = False Then        'only copy if the cell is not blank
                    If c.Interior.Color = firstGreyCell.Interior.Color Then
                        'if the interior color of cell 'c' is the same as 'firstGreyCell' then
                        Set nextDestCell = MasterSheet.Cells(nextDestCell.Row + 1, originalDestinationCell.Column)
                        'move the next cell down one column and back to the original column
                        nextDestCell.Value = c.Value 'copy the value to the recap sheet
                        nextDestCell.Interior.Color = c.Interior.Color 'copy the cell color too
                    Else
                        'if the interior color is not the same as 'c'
                        Set nextDestCell = nextDestCell.Offset(0, 2) 'move the nextDestCell to the right by 1
                        nextDestCell.Value = c.Value 'copy its value
                    End If
                End If
            Next c
        End If
    Next ws
End Sub

this is the code I have to copy the C column of my datasheets on a workbook. What the code about is when there's data in column C then copy the word there and paste it in the master sheet, but if it is blank then ignore and move along to the next row and loop through all the worksheets.

what I need is to make the condition if it is blank then go to column E and copy the data contained inside the cells and if the C column contain data, back to column C and copy the data

below I attach the picture my problem

please help me by changing the code so it will run as what I expected

thank you
