How give custom color on on the Survey report card?

View scorecard: (Option available on survey)

I want to change the "Agree" to Green color; OOB is picking up a Blue colour.

Hi, 
We have a few surveys that have the same metric result value. For example, "Poor" and "Excellent" are options that are used in a CSAT survey and an Internal Survey. So I want to give the "Excellent" metric result value a specific color but I only want it that color for the Internal Survey. How would I target a specific survey? 

Thanks!
