PPT图表( (723.8 KB)

ppt should be look like:

If I open the pptx in Powerpoint 2019, click on the Design tab, then hover over any of the icons in that ribbon, the colours change to reflect that Theme. Maybe a little more info on Microsoft site.

I guess that Powerpoint does this by applying offsets to the original colour leading to the mismatch of name to colour in the later slides. Maybe it is one of those feature/problems that MS so often come up with.
