RGBBlocks

RGBBlocks is a structured RGB building palette mod for Minecraft NeoForge.

The mod adds over 16,600 carefully generated building colors with a focus on smooth gradients, pastel tones, neutral materials, and architectural usability.

Each color includes three block variants:

• Normal
• Glow
• Glass

Unlike dynamic runtime color systems, RGBBlocks uses static full blocks for improved compatibility, stability, shader behavior, and mod interaction.

Features

• Over 16,600 structured building colors
• Pastel and neutral optimized palette generation
• Smooth gradient-focused color organization

Compatibility

RGBBlocks is designed around standard full-block behavior to maximize compatibility with shaders, building tools, and other mods.

The mod has been tested in both singleplayer and multiplayer environments.

Recommended Usage

RGBBlocks works especially well for:

• Architectural builds
• Gradient detailing
• Modern and pastel builds
• Chisels & Bits creations
• Pixel art
• Builds requiring precise color expression

Tested Environment

RGBBlocks has been tested with the following environment:

• Minecraft NeoForge 26.1.2.41-beta
• Chisels & Bits neoforge-26.1.2.11
• Iris NeoForge 1.10.9
• Sodium NeoForge 0.8.11
• Complementary Shaders
• Singleplayer and Multiplayer environments

The mod is designed around standard static full-block behavior for broad compatibility with shaders, building tools, and other mods.

Design Philosophy

RGBBlocks focuses on stability, simplicity, and large-scale color availability rather than dynamic runtime color systems.

The mod intentionally avoids complex runtime rendering or block entity systems in favor of predictable static blocks and broad compatibility with the Minecraft modding ecosystem.

Built for Minecraft NeoForge.

Known Issue (Chisels & Bits)

If a “Lost Connection” error occurs after updating RGB blocks while using Chisels & Bits, delete the clipboard .dat files inside:

.minecraft/chiselsandbits

This is caused by old Chisels & Bits clipboard data referencing outdated RGB block states.
