https://www.color.io/ The app creator has decided to close down this project in light of a job offer that competes with this app (presumably from Adobe or BlackMagic Design though currently unknown for sure). He made a version of his previously-only-web-based app available to download for pro subscribers. It will run on Windows, Linux, Mac, and a self-hosted web server. See the creator's farewell message here: https://web.archive.org/web/20251221193603/https://www.color.io/about All-in-one raw photo developer, film emulator and 3D LUT creator. One-of-a-kind color modelling that simulates the light response of film. Embedded in an intuitive, fun-to-use interface designed to get you twice the results in half the time. Create Color Managed 3D LUTs for nearly all apps. Exceptional tools for visionary creators. Every slider, curve and preset in Color.io is powered by an analog grading engine built for natural, film-like color and texture processing. So you can push your images as far as you need and still have them look untouched. AI Color Grading for instant look transfer with 3D LUT Export. Color Match uses AI to extract the color, contrast and brightness from reference images. Designed for photographers, filmmakers, and colorists, Color.io enables pro-grade color matching for RAW images and exports fully color managed 3D LUTs for DaVinci Resolve, Premiere Pro, Lightroom, Photoshop and more. Analog Curves for complete color control. Experience intuitive color curves driven by world-class analog color modelling. Non-linear is everything. Shape the exact density and brightness response or build your own vibrance models for every image. Filmic HSL for extreme color stability. Color.io comes with proprietary color refraction wheels that allow you to shift and compress colors with much higher color stability than any other tool. More than just Presets. The best film stocks in the world - at your fingertips. The Color.io Preset Library includes installable packs with hundreds of authentic film emulations — from Kodak Vision 3 200T, 500T, 250D to Portra 400, Cinestill 800T, and many more. These presets don’t just mimic the look of film - they replicate how film behaves. Built with analog-driven algorithms based on real film measurements, every preset is fully editable and customizable inside the app. Easily export every preset or custom look as LUTs or Lightroom Profiles, modify every setting, or create your own film emulations from scratch. Start in Color.io. Finish anywhere. As a look development tool, Color.io integrates into your existing workflows. Leverage industry-standard color management and open-source look transfer via 3D LUTs. A 3D LUT is a small file that allows you to apply the looks you've created in Color.io to videos, images and renders across apps and devices. Your colors will look exactly the same no matter where they're viewed.
