Change classic chart pen colors

I wish to change the pens colors of the classic chart, but I can’t find a way of doing so.
Is it possible at all?


It is possible.

In the chart customizer select the dataset properties tab. In the Dataset Renderer Properties group there is an entry for Series Colors. This indicates what colors a pen will be given in the order they are added to the chart.

You can change the colors here.

If you want to do it dynamically that’s a bit more complex, but your post doesn’t really indicate exactly what you’re attempting to do here.
