You can't do it using the native Excel interface, but a little macro
will handle it:

Sub PaintItBlack()
Dim srs As Series
For Each srs In ActiveChart.SeriesCollection
srs.Border.ColorIndex = 1
srs.MarkerBackgroundColorIndex = 1
srs.MarkerForegroundColorIndex = 1
Next
End Sub

I have multiple series on a chart, all with different marker shapes as
desired. How do I globally set all the data point colors to black without
picking each series in turn and setting a custom color.
