I've created two donut visualizations on my dashboard to see the overall traffic to my site based on mobile devices, and then the same comparison on a specific campaign page I am promoting via social media. The resulting donut visualizations default with either green or blue but they are representing exactly the opposite dimensions by color when looking between them - terribly confusing. Try as I might - I can't invert the colors to show the same dimension, even re-ordering the segments so they are hierarchically opposite. There's no apparent rhyme or reason to this. Editing colors would also seem to be an easy and effective enhancement for visualizations, any ideas?
