Chip can tell you about everything you will need to know on this subject.

Or you can probably edit this down to only count the red cells. You will
need to name ther range to be counted Data.
Sub ColorCount()
'Counts the number of colored
'cells in a range named Data.
Dim Blue5 As Integer
Dim Red3 As Integer
Dim Green4 As Integer
Dim Yellow6 As Integer
Dim Cell As Range
For Each Cell In Range("Data") '("B1:F11")
If Cell.Interior.ColorIndex = 5 Then
Blue5 = Blue5 + 1
ElseIf Cell.Interior.ColorIndex = 3 Then
Red3 = Red3 + 1
ElseIf Cell.Interior.ColorIndex = 4 Then
Green4 = Green4 + 1
ElseIf Cell.Interior.ColorIndex = 6 Then
Yellow6 = Yellow6 + 1
End If
Next
Range("A1").Value = Blue5 & " Blue"
Range("A2").Value = Red3 & " Red"
Range("A3").Value = Green4 & " Green"
Range("A4").Value = Yellow6 & " Yellow"
MsgBox " You have: " & vbCr _
& vbCr & " Blue " & Blue5 _
& vbCr & " Red " & Red3 _
& vbCr & " Green " & Green4 _
& vbCr & " Yellow " & Yellow6, _
vbOKOnly, "CountColor"
End Sub
