Elder guardian particle is rendering too dark

I'm unable to reproduce. Do you use any resource packs? What are your system specs?

I'm not using any resource packs. It is so strange that you can't reproduce this because I can reproduce it everytime.

I am able to reproduce this issue. I assume this only happens on certain GPUs.

As I'm using a NVIDIA GPU I assume this issue only happens on AMD graphics cards then.

Seem to be fixed for me in 19w45a.

Confirmed fixed.
