An extended, multi-language fork of EV3-ColorRGBEnhanced-Block — adding a distance-based Color Classifier in the Data Operations tab so your EV3 robot can tell colors apart even under changing light.
The stock EV3 color sensor only distinguishes 7 named colors and exposes reflected/ambient light. For competitive WRO / FLL robots you want raw RGB, illumination-invariant ratios, and a way to classify against your own color palette. This project bundles all of that:
- Original Color Sensor RGB Enhanced block (Sensor tab) — surfaces raw R/G/B, HSVL, and a tolerance-based comparator.
- New Color Classifier block (Data Operations tab) — normalize, define up to 8 reference colors, compute distances, pick the closest match.
All UI strings are localized into 15 languages.
