I have a report created in Desktop (Version: 2.72.5556.701 64-bit (August 2019)) with multiple pages mainly populated with 3 or 4 different line and clustered column charts. Data colors are consistent for each chart in each page. For example, all America data shows as teal columns, APAC is dark blue, EMEA light blue and the line showing historical data is orange.
When I publish to the Power BI Service the colors usually remain the same. Every once in a while something changes but for the most part the colors match the Desktop version.
However, when I export from the Service to PowerPoint the colors in the charts all change. They keep the same theme colors I'm using but seem to randomly change across the slides. America columns are now teal on one slide, light blue on another slide, dark blue on the next. Same for the rest of the columns and the line. On some slides colors for the same data series are different.
I can live with colors in the charts changing during the export but can't live with them showing different on each slide. The PPT colors need to be consistent for each series across all slides.
Am using a custom theme but have the same issue when I change the theme back to the default Power BI theme.
