Palettinator

Players can browse, generate, preview and publish block palettes from inside the game. A graphical interface is built into the mod, and a gradient command produces a smooth colour transition between two blocks, for example white and blue concrete, taking the blocks held in the main hand and the off-hand as its two inputs. Saved palettes can be reused as well.

The mod is designed around sharing and suggestions. A palette can be sent straight to another player, written into a book the player carries, or shown with its blocks listed by row. Search results draw actual block faces instead of coloured squares, and the suggestion feature ranks real building blocks, with the common ones first, so a single click loads a palette. It can also analyse a palette and report what is wrong with it, for example blocks that do not go together.

Installation is Fabric-only and needs Fabric API on the server. Only the server needs the mod for full function, since vanilla clients receive chat results with clickable links and colour swatches. Players may install the GUI client-side for extra features, and a resource pack is required for the block textures. The mod is published for 26.1.2 and 26.2, and all rights are reserved.
