ColorfulBlock
by MyDebugStick
ColorfulBlock is a NeoForge decoration mod that adds paint-able blocks whose six faces can each take a separate color.
What it does
The blocks are lightweight by design and come in solid color variants, which a color brush tool can apply to a block. Each of the six faces of a block can be colored independently, and colors are kept when a block is mined or picked with middle-click. Only NeoForge is supported, for the single version 1.21.1, and the mod has no further required dependency beyond NeoForge itself.
Players open a color picker by right-clicking with an empty hand, or by sneaking and right-clicking. The picker shows a 3D preview of the block that can be dragged to rotate and clicked to select a face. Colors can be set with HSL sliders, a HEX input, or by picking a color from an image or pasting one. Sneaking and right-clicking while holding a block lets a player edit its colors before placing it, and right-clicking a Color Block picks up its face color.
A server running it needs every connecting player to have it too. It works standalone, alongside other mods, and is released under the MIT License, though it is not open source. The latest file, 1.0.0 for 1.21.1, was published on 2026-07-24.
Key features
Paint-able blocks
Blocks carry six faces that can each hold a different color, applied once per face through the picker.
Solid color variants
Solid color versions of the blocks are available, and a color brush tool applies them to existing blocks.
Color picker interface
A GUI with a draggable 3D preview, HSL sliders, HEX input and image color picking edits the colors of a block.
Colors kept on mining
Painted colors are preserved when a block is mined or picked with middle-click, so a block can be moved without losing its paint.

How it compares
Pigmentum API is also a NeoForge option, released under the MIT License and open source, for 1.21.1 in the client and server environment. Pixel Painter covers the same NeoForge version and environment, but is closed under All rights reserved, so its code is not open. MCPaint is open source under the GNU General Public License v3.0 only and targets Forge and NeoForge for 1.12.2 – 1.20.1, a range that does not include 1.21.1.
