About this game
Welcome to Project Chromata
Project Chromata is a minimalist sci-fi idle game with a deep, unfolding mystery. You awaken as the Chroma Engine, a machine built for a single purpose: to create. In a silent, starless void, you must generate fundamental colors, combine them into increasingly complex forms, and reignite the memory of a lost cosmos.
Your Directive
The universe is empty. Your function is to fill it. Allocate your power, construct an evolving resource engine, and push back against the perfect nothingness. Each restored star becomes a new light in the dark and reveals another fragment of a forgotten story, bringing you closer to understanding what was lost and why.
Gameplay
Create & Combine: Generate primary colors and unlock advanced mixers to construct an intricate production chain.
Reignite the Stars: Transform your creations into Light and restore a vast, explorable Star Chart. Complete constellations to unlock powerful, permanent bonuses.
Automate Everything: Evolve the Chroma Engine with sophisticated automation that manages production and upgrades, allowing you to focus on restoring the cosmos.
Discover the Past: Recover fragmented records from the void and uncover the truth behind the universe, your creators, and your purpose.
Complete the Journey: Experience the complete story of Project Chromata, from the first spark of color to the final stage of the Chroma Engine’s journey.
From the Developer
Thank you for joining Project Chromata. The complete game is now here, bringing its full story and progression together from beginning to end. What began as a small experiment has grown into a journey across color, Light, forgotten worlds, and the mysteries beyond the stars. I hope you enjoy uncovering everything the universe has been waiting to reveal. Your feedback and support have helped shape Project Chromata, and I am deeply grateful to everyone who has joined the journey.

Hello, Chroma Engineers!Some more game patches! Remember, if you have any suggestions, use the feedback function and I will maybe make it true! Patch Notes - Version 2.1.2GLOBALAdded: Bug reports now detect local crash reports and let players preview and explicitly include them when submitting feedback.Changed: High Yield's default algorithm is now labelled Stable and explains that its safety buffer favors uninterrupted production while manual PIP allocation can achieve higher peak output.Improved: The Help Codex now distinguishes Compression's production speed, Light value per stored Essence, and effective Light yield over time.VOID DIVEFixed Bug: Closing or leaving a Void Dive during the Probe Lost animation now grants the run's earned rewards and records its progress.Balance: Void Dive speed scaling is unchanged through Tier 50, then grows at half the previous rate. Tier 100 is now 38x instead of 50.5x speed.STAGE 1Fixed Bug: Fill Bottom-Up now budgets maintenance through the entire production chain, preventing completed lower tiers from draining when any higher tier starts filling.STAGE 3Added: Stabilized hexes with exhausted discoveries can be extracted individually for one million of every Ethereal resource, clearing them for construction without affecting other sectors.STAGE 4Fixed Bug: Tower specialization buttons no longer flicker or ignore clicks while Crystallized Light is changing.Fixed Bug: The global resource meter in Landmark Assault no longer collapses when the sidebar is crowded.Improved: Landmark Assault's Crystallized Light reserve now uses larger outlined numbers and a higher-contrast meter for readability at every fill level.Added: Realm Assault now has an in-game How to Play button that pauses safely, a first-assault objective hint, and an introductory tutorial that returns if interrupted.STAGE 5Fixed Bug: Auto-Subvert no longer leaves the visible Home World map and creates thousands of inaccessible reports.

Project Chromata Update - Version 2.1.1
Hello, Chroma Engineers!I am back with some more patches and bug fixes! A special thank to dedicated Chromatic Friends: Rhomb and Kitty_Cat.0702 With their help, the game has Croatian and Traditional Chinese translations!

They stay unlocked across resets and when you load an older save file.GLOBALAdded: The credits have been updated with a new Chromatic Friend section.Fixed Bug: Loading an earlier save or resetting no longer carries late-game state over.Fixed Bug: The browser version no longer crashes when your browser's storage is full. If you have been hit by this, open Settings and export your save to a file first, then clear the site data for the page you play on and import the file back in, otherwise your progress will be lost.LOCALIZATIONAdded: Croatian and Traditional Chinese are now available as game languages.Added: The Novel is now fully translated in every supported language.Added: The Novel reader has its own language picker, so you can read it in a different language than the one the game runs in.VOID DIVEBalance: Deep tiers and Realm Dives are no longer overcrowded with enemies.STAGE 1Fixed Bug: Fill From Bottom no longer runs the fill tier so hard that the colours feeding it go negative.STAGE 3Fixed Bug: Ethereal resources now show their real rate.

Project Chromata Update - Version 2.1.0
Hello, Chroma Engineers! The time has come to unleash the Supporter Pack, featuring the complete Chromata Novel and the Reverie combat expansion with its map editor.Some of you may like the idea of a Supporter Pack, while others may not. At the end of the day, it is entirely optional and exists for those who want to support the continued development of Project Chromata.Still, I could not help myself. I wanted to make sure it included something fun and meaningful for anyone who chooses to pick it up.It has been slightly over a year since I first started working on Project Chromata. Without your help, feedback, encouragement, and support, the game would never have come this far.Thank you for being part of this journey.Nevertheless, the chromatic effort to make Project Chromata even better continues!Patch Notes - Version 2.1.0GLOBALImproved: Music and SFX volume are now drag sliders with a typeable percentage box, instead of stepping buttons.Fixed Bug: Tabs are no longer cut off when they do not fit. The bar shrinks them first and scrolls if it still runs out of room.Added: Touch devices can now drag to pan and pinch to zoom the Fractured Void, the Realm map and the Home World.Fixed Bug: Touch input on iOS is no longer offset from where you actually pressed, which made dragging and steering unreliable after a reload.VOID HUNTBalance: The Signal Uplink run upgrade now also lowers the per-level growth, so it still helps once the base requirement is at its minimum.Improved: Signal Uplink is no longer offered as a level-up choice when it can no longer reduce anything.VOID DIVEBalance: Stabilizers now grant +1% depth during a Realm Dive. They previously gave only charting and stability, which a Realm Dive discards, so charging them cost signal for nothing.Added: A box next to the tier buttons lets you type the tier you want to dive instead of clicking through them.Balance: Diving a high tier and dying immediately no longer pays out. The tier multiplier now only applies to w...Read full article on Community Announcements (arboraeternum)Patch NotesOfficial
