How to change color depending on a value // Mathcad prime 10

[JA_11566101]

Hi,
PTC made this good video showing the new features of Mathcad prime 10. But they did not make any guides or tutorials in how to make it work. 

You can see the feature in action here, where the text box change from "PASS" to "FAIL" and the color change from green to red. I want to make that, but I don't know how:

Basically I want to make the exact same thing. I have a foundation calculation which have multiple checks. Basically I have a load and a calculation which gives med the max load on the foundation. Here I have made a simple "if" formula which give me "OK" or "Not OK". But they do not have color. I need to change the color manually. 

I have this:

When I saw the feature in the above video, I knew that would make the calculation so much better. But I simply don't know how to do it? 

I have tried Input/output -> Controls -> Advance -> Text box

I have the feeling that this i super simple but I cant find anything of it when I google. But maybe I am searching for the wrong things. 

Hope somebody can help. Thx.

Wow thank you very much! That help a lot! 
I didn't realized input could be matrices that served as value and max value.
