After you define a KPI, will be awesome if you can color them:

* By expressions:

Red if number is less than 33.

Yellow if number is grater than 34 and less then 50.

Green if number is grater than 51.

* By scale:

A gradient from Red to Green (with yellow in the middle) and values from 0 to 100.

* Static:

Just color this KPI number purple.

NOTE: Colors and values must be configured by user.
