Custom Styles in Kinetic Application Studio

Let me preface that I already saw this thread and I was going to ask there, but the site scolded me not to necropost and occasionally try to behave myself.

Custom styling Kinetic components in App Studio?

Has anyone come up with a clever way to get more than the base four styles of OK, Warning, Error, Highlight in Kinetic?

I also know this is out there too: allow more color options for fields in kinetic Grid

I believe you can add new styles through the styling tools, which can be a PITA to use, so I opt to just make custom color controls in code and apply them with row rules that way.

I’m sure in the customization guides there is something about how to use the styler.

I’ve been trying to find any info on styling in Kinetic but I’m not finding anything that’s not related to the classic UI.

Am I missing a way to even have custom row rules like we had in classic? I am admittedly still learning how to do things in Application Studio. I have yet to find a replacement for Custom Conditions or Custom Actions like we had in Classic. It’s certainly not in the Data Rules as far as I can tell.
