I use the data filer function a lot. Whe a filter is turned on, the drop
down arrow turns blue. If tere are a lot of columns in the report the blue
arrow can be difficult to distinguish from the black arrows. Is there a way
to change the color of the arrows to something more obvious than blue, let's
say yellow?

Nope.

But maybe you could do something else...

I saved this from a Tom Ogilvy post:
====================================

http://j-walk.com/ss/excel/usertips/tip044.htm

to get it to refresh:

=FilterCriteria(B5)&left(Subtotal(9,B5:B200),0)

this is one I wrote back in 2000

Here is a user defined function that will display the criteria in a cell:

Public Function ShowFilter(rng As Range)
Dim filt As Filter
Dim sCrit1 As String
Dim sCrit2 As String
Dim sop As String
Dim lngOp As Long
Dim lngOff As Long
Dim frng As Range
Dim sh As Worksheet
Set sh = rng.Parent
If sh.FilterMode = False Then
ShowFilter = "No Active Filter"
Exit Function
End If
Set frng = sh.AutoFilter.Range

If Intersect(rng.EntireColumn, frng) Is Nothing Then
ShowFilter = CVErr(xlErrRef)
Else
lngOff = rng.Column - frng.Columns(1).Column + 1
If Not sh.AutoFilter.Filters(lngOff).On Then
ShowFilter = "No Conditions"
Else
Set filt = sh.AutoFilter.Filters(lngOff)
On Error Resume Next
sCrit1 = filt.Criteria1
sCrit2 = filt.Criteria2
lngOp = filt.Operator
If lngOp = xlAnd Then
sop = " And "
ElseIf lngOp = xlOr Then
sop = " or "
Else
sop = ""
End If
ShowFilter = sCrit1 & sop & sCrit2
End If
End If
End Function

=ShowFilter(B5)&left(Subtotal(9,B5:B200),0)

would show the filter for column 2

I usually put these functions in cells above the filter
