a color block mod
by ragsu2945
Colour Block adds a block that changes colour when a player right-clicks it, and that also cycles through colours on a timer or from a redstone pulse.
What it does
Right-clicking the block picks one of 16 colours at random, and a colour can be emitted as light, with white glowing brightest and black giving no light. The block can also change colour automatically, which a redstone pulse triggers. Mining it with a pickaxe returns the block, and without a pickaxe the player receives 9 Colour Shards instead. Nine Colour Shards craft back into a Colour Block, and a custom recipe combines a white concrete block surrounded by 8 dyes into one.
Shaders from Iris, OptiFine and Semi are supported for the light effects. The mod adds its own creative tab. Installation requires Fabric API, and the files are for Fabric only, covering 1.20.1 – 1.20.6. The server and every player need the mod, because the environment is client and server. The source code is public and the mod is open source under the MIT License, first published and last updated on 2026-03-28.
Key features
Random colour cycling
A right-click cycles the block through one of 16 colours chosen at random.
Colour light levels
Each colour emits a different light level, so white glows brightest and black gives none.
Mining and recovery
Breaking the block with a pickaxe returns it, and breaking it without one yields 9 Colour Shards.
Shard crafting and recipe
Nine Colour Shards craft back into a Colour Block, and a white concrete block surrounded by 8 dyes produces one.

Use cases
Decorative builds
Builders can place the block to add shifting colour to rooms, signs and light displays, with the glow varying by colour.
Redstone contraptions
A redstone pulse can change the block's colour, so circuits can drive its appearance without manual clicks.
Who it’s for: Players who want a colour-changing decorative block for builds, and server owners who run Fabric with Fabric API and want the content on a shared world.
How it compares
ChatColourMod is client-side only, published for 1.21.10 – 1.21.11 and released under the MIT License, so it does not change blocks at all. MCRGB is also client-side only, uses the CC0 1.0 Universal license and is open source across 1.19.2 – 26.3. Concrete Extras shares the client and server environment of this mod, is licensed under the MIT License and covers 1.20.4 – 1.21.
