Unidye

Unidye adds custom dyes made by combining vanilla dyes or other custom dyes in a crafting recipe. Each custom dye shows a color that depends on how it is used, because vanilla dyes already give inconsistent results across blocks, wool and terracotta. Dyeing terracotta with a custom dye produces a custom terracotta with the matching color, and the same applies to concrete, concrete powder and glass. Already dyed custom blocks can be dyed again, and the resulting block color is a mix of the dyes applied. Dyed leather armor can also be redyed. The dye count is raised toward a very large number of possible combinations.

Custom dyes can color pet collars, sheep's wool, fireworks and beacon beams, and they support other dye-related uses. Right-clicking a water cauldron cleans custom or vanilla dyed items. A command lets a player give themselves a custom colored block by specifying the color. The mod is published for Fabric only, across 9 release versions, and it is not open source. Both the server and every player need it, and the required dependency Polymorph must be installed. A stick is still needed when crafting custom dyes, whether or not Polymorph is installed.
