Conditional formatting based on years within timeframe

Hi all,

I'm wondering whether there's a faster/better practice approach to what I'm doing:

Basically I'm trying to create a report on a hardware lifecycle.

Lifecycle looks like this: 

So everything within a 5year timespan is fine, anything older needs a refresh or has no support

My Table looks like this:

Mapping | Generation | Last Supported Build (Refresh)

Now what I'd like to be able to do dynamically is use conditional formatting based on where a model is in it's lifecycle, i.e. if it's within 5 Years of e.g. YEAR(TODAY()) it's green, if it's in year 6 it's amber, if it's >6 Years it's red.

Column Generation is set as Date (yyyy). I also have a measure for Current year = Year(TODAY()). I have created a new column as 

Aging = [Current Year]-'HW Lifecycle'[Generation] which gives me the difference, in my case values from 1-9 as 2012 is the oldest year.

In conditional formatting I have used this, but I'm wondering whether there's a smoother way to do this, e.g. via a measure?

(I have a different measure foe something else that I created to be used in conditional formatting: 

Color Today = if(FIRSTNONBLANK('Waves'[Date],TODAY()) <today(),"#01B8AA","#fd817e"), so maybe there's something similar for the above scenario. I just couldn't figure it out)

Any tips are greatly appreciated 🙂
