The most recent snapshot updated their palletes to match the rest of the color changes, and they look great! Only problem htough…is the regular(purple) shulker box, while it does look good it looks weird on shulkers, and they no longer blend with purpur blocks.

The easiest way to fix this, is make it so there's a regular shulker box, with the original texture, and the new purple one is a dyed version. Similar to how Hardened Clay(Now Terracotta) works.
