Help with the d*** fitness-circles ;)

Hey all!

I'm currently in the process of trying to make my own skin. Not really a skin as such, just some fine-tuning of the base-skin

Now I've come across a problem I can't seem to find a solution to on my own (most other problem can "easily" be solved by just digging through enough of the .xml's ).

I want to change the values for the fitness-circles, so, let's say, it doesn't go dark green unless my player is at at least 95% instead of the 90% (I think) that is the standard value.

I know where to change the colours - but not the values that controls when the colours change :/

Anyone in here with a little guidance, maybe?

Best to all of you!
