countif cell is shaded

I have applied conditional formating to several columns of
data. Cells are shaded grey with a red font if they are
less than a certain threshold. Each column has different
criteria in the conditional formating.

Is there a way to count the number if cells that are
shaded.

Thanks

Sorry...this threw me off:
"...Cells are shaded grey with a red font if they are less than a certain
threshold."
 
Tim,

I think that you need to do a test on the same condition that you used in
the conditional format. So for instance, if they are shaded red if they are
less than 500, use the formula provided. In other words, replicate your
conditional formatting formula.

Or ....

You could try this technique that evolved out of previous threads between
Harlan Grove and I. Create a function to get the colorindex of cells, namely

Function ColorIndex(rng As Range) As Variant
Dim cell As Range, row As Range
Dim i As Long, j As Long
Dim aryColours As Variant

If rng.Areas.Count > 1 Then
ColorIndex = CVErr(xlErrValue)
Exit Function
End If

If rng.Cells.Count = 1 Then
aryColours = rng.Interior.ColorIndex

Else
aryColours = rng.Value
i = 0

For Each row In rng.Rows
i = i + 1
j = 0

For Each cell In row.Cells
j = j + 1

aryColours(i, j) = cell.Interior.ColorIndex
Next cell

Next row

End If

ColorIndex = aryColours

End Function

Put this in a normal code module. To use it, either add a helper column, say
in B1, put
=ColorIndex(A1)
and copy down column B. Then in C1, add
=COUNTIF(B1:B100,10) where the 10 is the colour you wish to test, or
=COUNTIF(B1:B100,ColorIndex(C2))
where C2 is given the colour you want to check

Or if you want to do it in one fell swoop

=SUMPRODUCT(--(colorindex(A1:A100)=10))

or if you want to test directly the colourised cell

=SUMPRODUCT(--(colorindex(A1:A100)=colorindex(C2)))

One major problem you should b e aware of is that if you change a colour in
the target range, the formula does not recalculate as the interior colour
doesn't trigger calculation, so you have to force it by editing the cell.
 
Gord,

Absolutely right, mea culpa! My technique is for normally coloured cells.

My first comment is the only one that stanmds in that case.
