Hide the effects of potions and arrows!

New mechanics
Minecraft has the ability to hide an item's enchantment or effect when given out using cheats. Why not add the same mechanics without cheats? With a workstation or crafting, you can remove information about the effect of a particular potion or arrow from the player.

How will this be implemented in the UI?
Potions and arrows have a certain colour depending on the effect. When we "erase" the information, the items will lose colour and turn black. Hence there could be a craft for this mechanic: an ink bag or black dye that "obscures" the original colour and doesn't make it clear what effect the player will get.

How to fit such mechanics into the world?
Actually, there are a lot of ideas.

• I came up with this mechanic to create a trap for the careless player. Let's say Steve finds an arrow with an unknown effect in a chest, takes it and moves on. When he encounters a mob, he shoots it with his bow and discovers that these arrows give regeneration. The player didn't think he'd made it worse for himself.
• Part of the social interaction on the servers. As a big fan of SMP projects I am ready to organise an auction of arrows and potions with unknown effects, because it's excitement: you do not know what you can get from another player.

Example of an unknown potion for Java 1.21
