Apeiron
by wiglaf
Apeiron is a Fabric decoration mod that lets players paint placeable blocks in any RGB shade across 24 block types.
What it does
Holding the Color Wand brings up a picker with a hue wheel, RGB sliders and a hex field, plus a history of recent shades. The chosen shade is applied to a block and stored on that block itself, so it survives world saves, chunk reloads and multiplayer sessions. Each block type comes in several texture variants, which together give over 2.8 billion block combinations.
The mod suits cottages, modern builds and large megastructures where a vanilla palette falls short, for example when an exact shade of teal or a warmer beige than the vanilla blocks is needed. It is a Fabric mod for the client and server environment, so both the server and every player need it. Files are published for seven release versions 1.21.1 – 1.21.11, with 1.1.0 for 1.21.11 as the latest file, under the MIT License. The mod is not open source.
Key features
Full RGB color range
Each block can take any color from the full RGB range instead of a fixed set of dye shades.
24 block types
Colors can be applied across 24 block types, so one palette covers walls, floors and trim.
Texture variants
Block types carry several pattern variants, adding up to 29 textures for a more varied look.
Persistent colors
The color is saved with each block and carried through world saves, chunk reloads and multiplayer play.

Use cases
Cottage and modern builds
Players can match exact shades to a design that vanilla blocks cannot reproduce.
Large megastructures
A single palette of recolorable blocks keeps big projects consistent across many areas.
Who it’s for: Builders who need precise colors for houses, interiors or large structures, and server owners who want a shared colored palette for players on a Fabric server.
How it compares
RGB Paintbrush is a Fabric mod for 1.21.1, under the MIT License, and is not open source; it is client and server like Apeiron. Colorful Blocks is also Fabric and client and server, released under the MIT License and open source, with files for 1.21.1 – 26.1.2, a wider range than Apeiron. Cobblemon EV Limitless is a server-required mod with optional client use, open source under the MIT License and published for 1.21.1, so it covers a different purpose.

What the author says
Each block type comes in multiple pattern variants, giving you over 2.4 billion possible block combinations. That's not an exaggeration. That's 16 million colors × 24 types × multiple textures, and every single one is placeable in survival. Whether you're building a cozy cottage, a modern megastructure, or anything…
