The two mods run fine, but it seems the moon is not colored red during a blood moon event.

That's on lumien's end.

Instead of unsafely ASM'ing into the renderSky method he could've just made a chaining worldprovider and change the moon color passed onto the sky renderer.

Uncertain if this is actually doable without ASM - or rather: doable in a mod-compatible manner...

Welp, not much i can do at my end for this besides writing specific integration for this. Looking about bloodmoon's calculations for this, i would rather decline on that one... So, gonna close this.
