Exordium v1.0.0 and v1.0.1, Fabric API 0.62.0, MC 1.19.2, Fabric Loader 0.14.9

Hm thinking about it. This one might not be fixable. They are not transparent, they invert the color I think. I can't replicate that, having them part of the rendering like that. Will have to check what can be done.

I think it should just be a different blending mode, that's how it works on images (e.g. try creating a layer on GIMP and changing its blend mode)

Yes, but since it's part of the everything right now, can't exactly just do that. Might need to relocate the draws to outside the buffer logic.
