Spirit orbs as well as the small pool and orb floating on top of the infuser have a red-only gradient, suggestion to have these resources in the assets folder so resource packs can change their textures/colormap.

that texture gets a red tint over it as more souls are added, that can't be changed.

it can be since i made the orb colors configurable (i didn't forget that one)

So it will be available in the next release?

yep
