I assume you have a chart with more than one data series?
Experimentation seems to suggest the answer is NO, but of course all (many)
things are possible with VBA
This will make them all aqua
Sub MakeColor()
ActiveSheet.ChartObjects("Chart 1").Activate
myCount = ActiveChart.SeriesCollection.Count
For j = 1 To myCount
ActiveChart.SeriesCollection(j).Select
With Selection.Interior
.ColorIndex = 8
.Pattern = xlSolid
End With
Next j
End Sub
