Rainbow Wood

Rainbow Wood adds new tintable versions of the vanilla wooden blocks and items. The set includes planks, stripped logs, stripped wood, fences, fence gates, pressure plates, hanging signs and chest boats. Players start with the uncolored versions, which drop from normal wooden items, and dye them afterward. A cauldron filled with water is used to apply the dye.

Colors are applied in two ways. The default method averages the color of the input items and gives the output that average. Items of the same type can also be combined, so a red planks block and a blue planks block produce two planks with the averaged color. Stairs, slabs and sticks follow the same rule, but a stair cannot be combined with a slab dye, and the inputs must share a color. The mod is built on Fabric API, and it runs on client and server, so the server and every player need it. It is released under the MIT License and is open source.

The author notes that vanilla offers only 11 wood types, while the full RGB range gives a far larger number of possible colors, and many of those look nearly identical. The tintable items are meant to fill the gap between the standard woods and the colors a player can actually tell apart. Files are published for Fabric only, for 1.21.1, and the latest file is 1.1.0+1.21.1, dated 2025-04-27.
