How to Dynamically Overlay Item Textures?

[Hipposgrumm]

I am trying to recreate the armor trims from the 1.20 snapshots (I'm doing it, ME!, don't steal, I want to be the one to do it!) and I am trying to make it so that I can overlay the trim texture (tinted with a color) with the armor item texture. I'm not creating json files for each trim because I want them to be dynamic (modded trims on modded armor, like manasteel trim on emerald armor). Can anyone tell me how to do this?

Also, it's worth mentioning that I mentioned this on Discord 3 times with only the third one being answered with saying no-one knows how.

So vanilla does this by using a permutation source asset with generates the overlaid assets on top of one another. You could do the same with a model loader or by creating your own source asset by copying the one in 1.20.
