I have a file that I want to import the data that have been coloured using Conditional formatting

I have code to open a file, but need this amended to only copy the data that has been coloured containing conditional formatting

Your assistance in resolving this is most appreciated

Sub Open_and_CopyFile()

 '
      
        Application.ScreenUpdating = False
     Application.EnableEvents = False
     Application.Calculation = xlCalculationManual
     Application.DisplayAlerts = False
    Dim nb As Workbook, ts As Worksheet, A As Variant
    Dim rngDestination As Range
  
    Sheets(1).Select
    Set ts = ActiveSheet
    
    On Error Resume Next
    Set rngDestination = ts.[A1]
    On Error GoTo 0
    If rngDestination Is Nothing Then Exit Sub
    ChDir ("C:my Documents")


With Application.FileDialog(msoFileDialogFilePicker)
.InitialFileName = "*Conditional*.xls*"
If .Show = 0 Then Exit Sub
A = .SelectedItems(1)
End With


'   A = Application.GetOpenFilename
 '  If A = False Or IsEmpty(A) Then Exit Sub
    
    Application.ScreenUpdating = False
    
   Set nb = Workbooks.Open(A)
   ThisWorkbook.Activate
  
 
  
    
    
   nb.Sheets(1).Range("A3:D50").Copy
  
       rngDestination.PasteSpecial Paste:=xlPasteValues
    rngDestination.PasteSpecial Paste:=xlPasteFormats
    Application.CutCopyMode = False
       
    
    nb.Close savechanges:=False

    
         Application.ScreenUpdating = True
         
     Application.EnableEvents = True
     Application.Calculation = xlCalculationAutomatic
      Application.DisplayAlerts = False
     
End Sub
