Colorflow

# Colorflow — the in-game colour picker for Minecraft

> *Stop guessing. Pick a colour, get the nine closest real Minecraft blocks, and build a smooth, pixel-perfect gradient — all without leaving the game.

Colorflow is a lightweight, fully client-side mod that turns Minecraft into a professional-grade colour-matching and gradient tool. It uses the scientific CIEDE2000 (ΔE 2000) colour-difference formula — the same standard used by painters, designers and print workflows — to rank every block in your game (vanilla and modded) against any colour you want.

## Why builders love it

• 9 closest blocks for any colour, ranked by true ΔE 2000 perceptual distance (not a naive RGB guess).
• One-click gradients — pick a start and end block, and Colorflow generates a smooth 3 to 9 step gradient using real block icons and an ideal interpolated colour ramp.
• ΔE quality score — an “Average deviation ΔE” badge tells you exactly how close the gradient is, with a colour-coded rating (green ≤ 2, amber ≤ 10, red beyond).
• Fill your hotbar in one click — push the generated block stack straight into your hotbar (creative mode).
• Exact block IDs — copy the full list, or grab any block’s ID, hex, or name instantly.
• Eyedropper — sample the exact colour of the block you’re looking at and match it immediately.

## Real numbers, real results

| Feature | Value | |---|---| | Supported Minecraft versions | 28 (1. 19 → 26. 2, incl. 1. 20/1. 21 & 26.x series) | | Colour matching | CIEDE2000 (ΔE 2000) | | Closest-block results per colour | 9 | | Gradient steps | 3 – 9 (user-adjustable) | | Block database | Every registered block (vanilla + modded) | | Languages | 10 (EN, FR, DE, ES, IT, PT-BR, RU, JA, KO, ZH-CN) | | World/server dependency | None — runs entirely client-side |

## Match tab — the colour engine

A Photoshop-style HSB picker: a saturation/value square, a full hue spectrum, RGB channel sliders and a live hex field. As you move, the nine closest blocks update in real time with their block icon, ID, shape and a ΔE 2000 score.

• Left-click a match → get the block.
• Shift+click → copy the block ID.
• Right-click → set it as the gradient start.
• Filters: Full blocks only, Vanilla only, Hide tinted (grass/leaves/biome-coloured) — so you always get buildable results.
• Clipboard: copy / paste hex (#RRGGBB) from anywhere.

## Gradient tab — smooth block ramps

• Block browser with live text search (try “terracotta”, “concrete”, “wool”…).
• Set Start and End blocks, choose 3 to 9 steps, and see a live preview with real block icons plus the ideal colour ramp underneath.
• The Average deviation ΔE value measures how faithful the gradient is to the true colour interpolation.
• Fill hotbar, Copy list (block IDs), and Swap ends — all one click.

## Quick start

1. Install the jar for your Minecraft version (one jar per version — no guessing). 2. Press the Colorflow key (default: `C` — change it in Controls > Key Binds*). 3. Pick a colour, click a block, and build.

> Requires Fabric Loader and Fabric API. No server-side mod needed — works in singleplayer and on any server where you have client mods allowed.

## Supported versions

Every supported Minecraft version gets its own jar, exactly named for it:

1. 19 · 1. 19. 1 · 1. 19. 2 · 1. 19. 3 · 1. 19. 4 · 1. 20 · 1. 20. 1 · 1. 20. 2 · 1. 20. 3 · 1. 20. 4 · 1. 20. 5 · 1. 20. 6 · 1. 21 · 1. 21. 1 · 1. 21. 2 · 1. 21. 3 · 1. 21. 4 · 1. 21. 5 · 1. 21. 6 · 1. 21. 7 · 1. 21. 8 · 1. 21. 9 · 1. 21. 10 · 1. 21. 11 · 26. 1 · 26. 1. 1 · 26. 1. 2 · 26. 2
