We have a site that is brandable (colours) for each client. There is an area of the site that has donut charts that represent the following four items:
We thought of taking the client's primary brand color and using that as the successes and then having the other items the same color but lightened (15/20%)
This does not seem to work well due to the lack of control for the colors (errors as a green color?)
Is there an industry standard approach for these represented as colors? Maybe the traffic light system (Red = errors, Amber = warnings, Green = success)
And if so, what would be a good color for the fourth item (exclusions)?
Has anyone else had to represent this type of data through colors and how did it work?
