can confirm and create the issue
it seems that all potions get recolored based on the first one you have in your hotbar, of the same cataglory.

for example, if you have a splash potion of weakness in your hotbar then restart the game, all of your splash potions will be the color of weakness.

if you have lingering potion of slowfalling, theyll all be the color of slowfalling.

arrows are affected as well, following the same pattern
