What happened?

Firefly don't have colored ting - their body is white when their glow is colored. Bug exists in both 1.18.2 and 1.19

Correct shading (with tint) should look like this:

BetterNether

7.0.2

BCLib

2.0.5

Fabric API

0.56.0

Fabric Loader

0.14.8

Minecraft

1.19

Relevant log output

None

Other Mods

better-end-2.0.2
iris-mc1.19-1.2.5
sodium-fabric-mc1.19-0.4.2+build.16

Should be fixed in the just release 7.0.3 update.
