Maybe instead of only the tractor beam changing color, maybe include other things such as the tractor beam overlay, the wither storms eyes, the glowing effect during night, wither sickness texture, maybe even the fog in the bowels?

I haven’t played with the new tractor beams yet but this seems like how it should be. I don’t care for the wither sickness texture or the fog, cuz then people are gonna be asking for the blocks to be adjusted as well, but it’d only make sense if the eyes, beam overlay, and the glow matched the tractor beam

Most of things mentioned must be changed via resource packs, however the glow isn't and could use a config option

Will be possible in the next update via resource packs
