Dyed Cauldrons adds Bedrock-style dyed water cauldrons to Java Edition.
Use dyes on a water cauldron to tint the water, mix colors by adding more dyes, and use dyed water to color dyeable items.
The cauldron stores its exact color per-block (including via NBT), syncs correctly to clients, and preserves the dye until the cauldron empties.
(mod does not add any golden liquid, though you can get the color gold)
Commands (no item texture added for dyed_water_cauldron, but it is impossible to obtain in survival)
