How to count and sum "Condtional formatting" cells by color in Excel 2010?

I came across this post being unanswered. so here is a User Defined Function in VBA

to SUM 

use this UDF 

Function SumConditionColorCells(CellsRange As Range, ColorRng As Range)
Dim Bambo As Boolean
Dim dbw As String
Dim CFCELL As Range
Dim CF1 As Single
Dim CF2 As Double
Dim CF3 As Long
Bambo = False
For CF1 = 1 To CellsRange.FormatConditions.Count
If CellsRange.FormatConditions(CF1).Interior.ColorIndex = ColorRng.Interior.ColorIndex Then
Bambo = True
Exit For
End If
Next CF1
CF2 = 0
CF3 = 0
If Bambo = True Then
For Each CFCELL In CellsRange
dbw = CFCELL.FormatConditions(CF1).Formula1
dbw = Application.ConvertFormula(dbw, xlA1, xlR1C1)
dbw = Application.ConvertFormula(dbw, xlR1C1, xlA1, , ActiveCell.Resize(CellsRange.Rows.Count, CellsRange.Columns.Count).Cells(CF3 + 1))
If Evaluate(dbw) = True Then CF2 = CF2 + CFCELL.Value
CF3 = CF3 + 1
Next CFCELL
Else
SumConditionColorCells = "NO-COLOR"
Exit Function
End If
SumConditionColorCells = CF2
End Function

if you want to Count instead of SUM then use the below UDF

Function COUNTConditionColorCells(CellsRange As Range, ColorRng As Range)
Dim Bambo As Boolean
Dim dbw As String
Dim CFCELL As Range
Dim CF1 As Single
Dim CF2 As Double
Dim CF3 As Long
Bambo = False
For CF1 = 1 To CellsRange.FormatConditions.Count
If CellsRange.FormatConditions(CF1).Interior.ColorIndex = ColorRng.Interior.ColorIndex Then
Bambo = True
Exit For
End If
Next CF1
CF2 = 0
CF3 = 0
If Bambo = True Then
For Each CFCELL In CellsRange
dbw = CFCELL.FormatConditions(CF1).Formula1
dbw = Application.ConvertFormula(dbw, xlA1, xlR1C1)
dbw = Application.ConvertFormula(dbw, xlR1C1, xlA1, , ActiveCell.Resize(CellsRange.Rows.Count, CellsRange.Columns.Count).Cells(CF3 + 1))
If Evaluate(dbw) = True Then CF2 = CF2 + 1
CF3 = CF3 + 1
Next CFCELL
Else
COUNTConditionColorCells = "NO-COLOR"
Exit Function
End If
COUNTConditionColorCells = CF2
End Function
