Custom Potion Colors

[olduvaihand]

I've been getting my feet wet with modding through Kaupenjoe's youtube tutorials, which have been pretty solid, and am trying to go a little further than his examples. Current thing I'm stuck on is customizing potions.

I understand how to define and register potions and can successfully use them in the game. I see there's a field in the PotionContents data component for custom color that presumably overrides the default effect-color mixing behavior, but I'm confused about how to supply an override, either via PotionContents (which I assume you can do) or by providing a data file somewhere.

I've tried modifying the default component in a ModifyDefaultComponentsEvent handler, but no dice. I've found other posts from modders in early version of forge doing things like redefining the PotionItem class altogether. Any pointers from the experts?

Thanks
