It is not possible to change colors based on a threshold within the KPIs for DPM. To accomplish a goal similar to this, you could use the Needs Attention feature of DPM. On the home page, for each solution (i.e. a service) card, you can expose Needs Attention attributes (Open Incidents and ~7 others are set up OOB). The admin can set a threshold for moderate and severe statuses for each type of solution. When a count is severe, it is red. For moderate, it is amber. Otherwise, green. Cards are sorted with the most severe cards/solutions showing first. On top of these thresholds, each user of DPM can set personalized thresholds for these counts.
However, once you drill down to the details page for that service (as an example), DPM surfaces the needs attention counts on the right rail (and in greater detail), but does not surface the statuses from the home page. I will bring this up with our PM and designer as a potential feature to add.
