I have a texture pack on and it changes to look of player health GUI (like most packs, I think?) and I've been working pretty hard to streamline all of my textures, but there doesn't seem to be a way to change the color/look of the overlaying heart texture (like Tinker's Construct did back in 1.7.10)

Is there a way to add this option?
Unless this is an option already, just please point me to a place to fix it c:

The heart textures themselves are found here. Currently, there's no way to change the colors, but I plan to fix that soon. But color changes will likely be done in the mod's config file.

How did TCon handle heart colors, by the way? I never really used that mod much.

Got it to work!
I'm not sure code-wise how TCon did their hearts retextured. It's not in the latest version (since 1.8.9 I think? Don't remember) But I know it was in the 1.7.10 and 1.6.4 versions they had the heart levels. Maybe check out their repository?
