Выберите все цветные ячейки из условного форматирования

Я бы предложил что-то вроде этого:

Sub selectCFColours()
    Dim cell As Range
    Dim selRange As Range

    For Each cell In Range("K6:M200")
        If cell.DisplayFormat.Interior.Color <> cell.Interior.Color Then
            If selRange Is Nothing Then
                Set selRange = cell
            Else
                Set selRange = Union(selRange, cell)
            End If
        End If
    Next

    If Not selRange Is Nothing Then selRange.Select
End Sub

Следующий код предназначен для общего кода FindAll. Это также можно использовать, установив Application.FindFormat, чтобы его можно было использовать с условным форматированием.

Sub FindBlack()
    Dim FoundRange As Range

    With Application.FindFormat
        .Clear
        .Interior.Color = RGB(0, 0, 0)
    End With
    Set FoundRange = FindAll("", LookIn:=xlFormulas, SearchWhat:=Range("K6:M200"), SearchFormat:=True)

    If Not FoundRange Is Nothing Then Debug.Print FoundRange.Address
End Sub

Function FindAll(What, _
    Optional SearchWhat As Variant, _
    Optional LookIn, _
    Optional LookAt, _
    Optional SearchOrder, _
    Optional SearchDirection As XlSearchDirection = xlNext, _
    Optional MatchCase As Boolean = False, _
    Optional MatchByte, _
    Optional SearchFormat) As Range

    'LookIn can be xlValues or xlFormulas, _
     LookAt can be xlWhole or xlPart, _
     SearchOrder can be xlByRows or xlByColumns, _
     SearchDirection can be xlNext, xlPrevious, _
     MatchCase, MatchByte, and SearchFormat can be True or False. _
     Before using SearchFormat = True, specify the appropriate settings for the Application.FindFormat _
     object; e.g. Application.FindFormat.NumberFormat = "General;-General;""-"""

    Dim SrcRange As Range
    If IsMissing(SearchWhat) Then
        Set SrcRange = ActiveSheet.UsedRange
    ElseIf TypeOf SearchWhat Is Range Then
        Set SrcRange = IIf(SearchWhat.Cells.Count = 1, SearchWhat.Parent.UsedRange, SearchWhat)
    ElseIf TypeOf SearchWhat Is Worksheet Then
        Set SrcRange = SearchWhat.UsedRange
    Else: SrcRange = ActiveSheet.UsedRange
    End If
    If SrcRange Is Nothing Then Exit Function

    'get the first matching cell in the range first
    With SrcRange.Areas(SrcRange.Areas.Count)
        Dim FirstCell As Range: Set FirstCell = .Cells(.Cells.Count)
    End With

    Dim CurrRange As Range: Set CurrRange = SrcRange.Find(What:=What, After:=FirstCell, LookIn:=LookIn, LookAt:=LookAt, _
        SearchDirection:=SearchDirection, MatchCase:=MatchCase, MatchByte:=MatchByte, SearchFormat:=SearchFormat)

    If Not CurrRange Is Nothing Then
        Set FindAll = CurrRange
        Do
            Set CurrRange = SrcRange.Find(What:=What, After:=CurrRange, LookIn:=LookIn, LookAt:=LookAt, _
            SearchDirection:=SearchDirection, MatchCase:=MatchCase, MatchByte:=MatchByte, SearchFormat:=SearchFormat)
            If CurrRange Is Nothing Then Exit Do
            If Application.Intersect(FindAll, CurrRange) Is Nothing Then
                Set FindAll = Application.Union(FindAll, CurrRange)
            Else: Exit Do
            End If
        Loop
    End If
End Function
