I'm currently getting great results with the compressed HSVA colour system workflow using coolors.co:

The above is the Mint PETG I have, and my workflow is to:

With this, I can get a confident compressed-HSVA mentioned in this log, but I still move the sliders around by 1 step to make sure I've got the right colour:

Confident YES:

Confident NO:
Confident NO:

There was no shine-through for the mint, thus the colour for this not-quite-cyan is 35.a9a.

Surprisingly, my pink is so much further away from the ideal magenta. The hue of the mint is only out by 5 degrees, yet the pink is out 25 degrees and admittedly desaturated:

It also has a bit of a glow when the filament is lit from behind, so its value could be 70.6a9.

One possibility for the hue is screen colour reproduction, and I know that pinks have always been questionable on various IPS panels. On my OLED phone, this same colours looks much more vibrant... oversaturated even. On my 9th gen iPad I happen to have, the hue is 315 and other values are unchanged. This is part of the reason for the compressed colour space; there are so many variables that the precise value isn't that meaningful. 

Considering a substantial amount of people have an unmodified iPad, touted with "TrueTone" technology, I will use it as the hue reference.
