The Bug:

Equipment outlines in the inventory are now slightly less opaque than they previously were.

This is likely intentional.

Steps to Reproduce:

1. Launch an instance of 1.19.3, join a world, open your inventory, and look at the opaqueness of the equipment outlines.
2. Launch an instance of 23w05a and do the same thing.
3. Take note as to whether or not equipment outlines in the inventory are now slightly less opaque than they previously were.

Observed Behavior:

Equipment outlines are now slightly less opaque.

Expected Behavior:

Equipment outlines would be the same opaqueness as they were in 1.19.3.
