MCRGB
by Bacco
MCRGB lets players search blocks by the dominant colours of their textures, and the colour picker lists matching blocks sorted by colour distance.
What it does
Blocks are indexed by the colours that cover most of their texture, weighted by how much of the surface each colour takes up. A colour picker takes an input colour and returns the blocks whose dominant colours sit closest to it, sorted by Euclidean distance. Hovering over a block shows a breakdown of its colours, the percentage each one covers and the block states those values correspond to.
Only the client needs the mod, so a single-player world or a multiplayer client can run it alone and servers need nothing. It requires Fabric API and Cloth Config, and it targets Minecraft 1.20.1 and newer. Files are published for Fabric across 20 release versions, 1.19.2 – 26.3, and the code is released under the CC0 1.0 Universal license, which makes it open source. Snapshot builds are not published.
Key features
Colour search
Blocks can be searched by the dominant colours of their textures, with a colour picker for choosing the target.
Colour breakdown on hover
Hovering over a block shows the percentage each colour takes up in its texture and the block states those values match.
Inventory info
Regular inventories show the same colour information for the items they hold, and a config option controls this.
Weighted colour matching
Each texture colour is weighted by how much of the texture it covers, so large areas count for more than small details.

Use cases
Finding blocks for a build
A builder picks a target colour and lists the blocks whose textures are closest to it, which helps when planning palettes.
Checking block colours
Hovering over a block reveals which colours dominate its texture, for comparing similar-looking blocks.
Who it’s for: Builders and resource pack authors who want to match blocks by colour rather than by name. Players who only need standard decoration can leave it out.
How it compares
Firorize is client-side only and open source under the MIT License, with Fabric builds covering 1.16 – 26.1.2. Custom Level Colour is also client-side only and open source, released under The Unlicense for 1.20.1 – 26.2. Totem Party Popper is not open source; it is a Fabric mod under a custom license for 1.19.3 – 26.3, and its client must be installed while the server may skip it, which makes it a different kind of mod from a colour search tool.

What the author says
You can also see the breakdown of a block's colour info by hovering over it. This tells you the percentage each colour takes up in each texture, and which blockstates it corresponds to. Optional: You can also view this info in regular inventories by changing the config. On first launch, MCRGB will generate a file…
