Match colours with precision using real-time RGB sliders in this fast-paced puzzle game with multiple modes, streaks, and daily challenges. Lumetra is a mobile-first colour-mixing puzzle game that challenges players to recreate target colours as accurately as possible using real-time RGB sliders. Designed for quick play sessions and smooth touch interaction, the game combines fast decision-making, colour intuition, and precision-based scoring in a clean and modern interface. Each round presents a target colour and gives players a limited amount of time to mix the closest possible match. Accuracy is calculated using perceptual colour difference methods, rewarding precise colour matching rather than simple RGB approximation. The closer the match, the higher the score. Lumetra includes multiple gameplay modes designed for different play styles and difficulty levels: • Classic Mode — Match a series of colours under time pressure with selectable difficulty settings. • Speed Rush — Fast-paced rounds with minimal time to react and mix. • Zen Mode — No timers or pressure, focused purely on colour exploration and experimentation. • Daily Challenge — A deterministic daily puzzle featuring the same target colours for all players on that day. Difficulty levels affect colour complexity and timing. Easier modes focus on vibrant, saturated colours, while higher difficulties introduce muted tones, greys, near-whites, and subtle shades that are harder to distinguish and recreate accurately. The game features: * Real-time RGB colour mixing * Accuracy-based scoring system * Combo streak bonuses * Animated visual feedback * Session-only best scores * Dynamic colour generation * Responsive mobile-first controls * Synthesised audio created entirely with Web Audio API * Offline-friendly gameplay with no external dependencies Lumetra is built with privacy in mind. The app does not collect personal information, use analytics, store gameplay data, or require accounts. No local storage, cookies, or tracking technologies are used. All game state exists only during the active session and is cleared when the app is closed or refreshed. With its minimalist dark-mode presentation, smooth animations, and focus on colour precision, Lumetra offers a unique puzzle experience suitable for both quick sessions and focused play.
