Consistent colors in reports

I'm using Adobe Analytics for the reporting of votes (e.g. go to work by bike) in diverse regions.

Due to the fact, that Adobe Analytics shows color according to the amount of votes, the reports is confusing to our users.

The votes for "By bike" are shown in orange in region A and are shown in blue in another region. This is because Adobe Analytics shows colors in the way that the highest item is always orange, etc.. If you want to compare one and the same item in different regions, then the report doesn't work anymore and is even confusing.

Why not allow the use of static colors, which can be attached to a data type?
