RGB Paintbrush
by inyaroslav52
RGB Paintbrush lets players paint any block in a full RGB color, choosing from more than 16 shades beyond the vanilla wool palette.
What it does
A brush picks a color from a color picker opened with the J key, then recolors a block with a left click. A right click copies the color of a block so it can be reused. Creative mode can craft the paintbrush, and it is not limited to a fixed palette. The mod runs on Fabric for 1.21.1 only, and it is published on the client and server side, so both need it installed. Fabric API must be installed as well.
RGB Paintbrush is released under the MIT License and is not open source. The Fabric file for 1.21.1 is version 1.0.0, published on 2026-05-16 on the alpha channel.
Key features
Unlimited color palette

Color picker and copy
The J key opens a color picker, and a right click copies the color of a block for reuse on others.
Precise gradients
Builders can create color schemes and gradients that vanilla blocks do not offer, with details matched to exact shades.
