Chad posted while I was typing so got there first - but “Training Readiness Indicator” seems to fit the intent.
Secondly, I’ve only been with TR since Dec '21, but TR slurped up my entire Strava history, so there’s data going back to 2010, including JRA, then structured solo work, then with a coach, then TR. If that’s of interest @Nate_Pearson, you’re welcome to it.

Blue in addition to or instead of green?
My assumption:
Per the comments above, we clearly see 2 colors on the calendar in Nate’s examples. It’s an apparent lack of color (normal white calendar day) that is the “Green” indicator. If so, I agree that RLGL naming implies a Green color will be used somewhere.
So if TR sticks with that color foundation naming, they really need to include the associated color in the indicator methods for the sake of consistency at the very least.
OK, so 4 colors for what purposes in your scenario?
Tapering or being race ready. Could also indicated that you’re not training enough and losing fitness. So you’re fresh (Blue). So being fresh when you want to (before a race) is a good thing. Being fresh (blue) mid week during a Build block, not good.
It’s really just a proxy for Form.
Musk we pay extra for this blue check?
This is a good point.
Still looking to understand how this differs from Form, beyond the fact that it is integrated in TR and it can give you a warning when you are about to start an activity.
4 colors makes it confusing in my book. I’d stick with 3, but use all 3.
RLGL doesn’t differ at all! Sorta, Nate states there is some AI/ML behind it all. It’s just TR’s version of ATL/CTL/TSB. But they better give the appropriate credit or some “people” may lose their sh$t on the forum! 
It is different. There are plainly some underpinnings of stress/strain from the tss model, but it also includes other data. Link to the timestamp where Nate talks about it.
I’d be really interested in what RLGL says about the following dates - these are all CTL peaks where I “crashed and burned” after. The 12/30 dates are all tied to Festive500, so it would be interesting to see when I’m Yellow, and when I go Red during Festive500

I mean there is always a “propriety blend”, “secret sauce” to everyone’s product. It does seem a bit more refined though, so looking forward to it to compare to Form.
It’s one of the things I find interesting about ML/AI models in general. If a model can derive something from the data that others have created from an equation. Internally the representation might be quite different.
Sort of like you can’t copyright a recipe. But you can copyright the ‘text’ that goes with the recipe.
Because any rational actor could combine ingredients in any number of ways to get a result that satisfies the constraint (it tastes good).
At least that’s my complete neophyte thinking around these things #notALawyerOrADoctor.
Of course predicating your model on pre-existing art/science might well influence the outcome.
Call it ‘Let’r Rip Tater Chip’
On reflection, I think most of more burned out phases or lack of progression are probably as a consequence of the additional non-training load (kids, work, travel). My garmin body battery metric seems to be a good gauge of when I should press on or take it easy.
Any scope for TR to take on data from my wearable? Even if it’s the user just manually entering a number, like with the gauging rpe post workout?
Excited for red light green light!!! You can’t call it anything else now surely!!
Thanks!
Would also love to be involved in the testing. Been on TrainerRoad a couple years. When I first joined I did a LV training plan and i seemed to go backwards.
I then sacked plans off and just picked workouts that I liked the look of. Also set targets of completing certain workout and working towards that. I then started using train now. One reason I didn’t use training plans is that I always go on a hard long group ride on saturday and wasn’t sure how I’d incorporate that in to a plan. I tried a polar plan towards the end of last year but a back injury put paid to that.
But I’d love to be involved and someone take a look at my history and see if or more to the fact where I could improve.
Call it the Loggins Index. 
Simply? Form Balance.
It’s interesting you say this, but my Garmin readiness has often told me I’m good to go when I’m not. I can tell from looking at HR and HRV, whether I’m really stuffed. It’s not reliable to tell me to take it easy.
I always get recommended anaerobic. I don’t do any regularly lol.
I am currently on a general base mid volume plan and I belive I am right on the edge of burnout and am curious if RLGL would be flagging me right now.
I recently had a prescribed 4h z2 ride that turned into an outdoor 6h ride with a lot of not z2… the classic move. Since then intervals.icu has shown me as dipping into high risk.
Today’s scheduled sweet spot workout will be pushing me back into high risk for sure.
I’m not overly concerned as I’m about to hit a rest week, but i am curious to see if RLGL aligns with intervals.icu and my own self perception of fatigue.
