Daily Heart Rate Graph color keeps changing (solid RED to Multicolor)

I honestly dont ming either one, i just want to understand the inconsistency, why some days one vs the other? 

Yeah, others have noticed this too.

Personally I noticed that all of my daily HR and activity HR charts are now (retroactively) changed to the new style, but other people have noticed a mix of styles like you.

It's kind of baffling. Almost like a weird form of A/B testing except I don't think that's how you're supposed to do it.

starting with red at the very low HR, with multicolor to signify the HR zone I'm guessing. 

Yeah, except that red is also used for zone 5, so it makes zero sense to also use red for the low HR. And others have also found that red is used for "middle" HR too.

Some ppl have posted multicolour charts where the lowest heart rates are red, values that are little higher (in zone 0) are grey, but values even higher than that (still in zone 0) are red again. Values even higher than that are coloured according to the zones.

Also, the "low reds" aren't just for very low absolute HR, but also for the lowest *relative* HR. Like if I look at a running activity, and my HR started around 100, that relative low at the beginning will be colored red (while the rest of the graph will just use the zone colours as usual).

But on the daily graph, my lows are obviously much lower (~50), and it's those relative lows which are colored red. An HR of 100 on the daily graph wouldn't be red.

Then ofc there's multicolour charts where the colours are only used for the zones and the relative lows are not red.

So really, I have no idea what Garmin is trying to do here.
