Doesn't change my hearts color with this mod installed, I tried changing the ID (Because I've read that Forge (And maybe Fabric too.) uses Alphabetical Order to arrange mods.) of your mod manually but I'm a complete potato with whatever we're supposed to do with the inside code so of course I've failed.

since the mod also adds its own colored hearts, try to go into their config file and see if it can be disabled. The config files are located inside a config folder in the game directory.

Thank you for the quick answer, but in the Config Files, there was sadly no way to change it.

I instead followed his advice and made a Resource Pack that changed the Hearts Color.

Sadly, the bars are only one color + base bar color.
