Colorflow

# Colorflow — the in-game colour picker for Minecraft **Thank you very much for [Elfi](https://www.instagram.com/elfi_draw) for the project icon!** > **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 --- ## Translations Colourful for everyone: fully localised in **English, Français, Deutsch, Español, Italiano, Português (BR), Русский, 日本語, 한국어, 简体中文**. --- ## Changelog — 2.0.0 - Rebuilt around **CIEDE2000** for precise colour matching. - Redesigned, performance-optimised UI (Match tab stays at a smooth frame rate even while dragging). - New **Gradient** tab with configurable **3–9 step** ramps and a ΔE quality badge. - **One-click hotbar fill**, block-ID copy, hex clipboard, eyedropper. - **10 languages**. - Published for **28** Minecraft versions.
