Luttie
Film emulation in a browser tab,
after Color.io.
Color.io's web app went offline on 31 December 2025, when its founder left to work on creative tools elsewhere; EU filings later showed Apple had acquired the company. If you used it for film emulation in the browser, Luttie does the same job: a film engine that models negative and print stocks, film grain, halation and bloom, and .cube LUT export.
What Color.io users lost.
The web app closed. Pro subscribers kept an offline desktop version.
No browser version
There's nothing to open in a tab any more — not on a borrowed laptop, a Chromebook or a client's machine. Only Pro users have the offline desktop app.
No way in for new users
Anyone who didn't already have a Pro licence can't sign up. Film emulation in the browser now means finding another tool.
No updates expected
Its founder has moved on, so the offline app isn't expected to gain new cameras, stocks or fixes.
Luttie vs Color.io
Color.io as it was at closure, against Luttie today.
Color.io's features are as reported at its closure by CineD and PetaPixel. We never had access to its internals, so this compares features, not image quality. Read CineD's report on Color.io's closure.
When to use Color.io. When to use Luttie.
Use Color.io when:
- You already have Color.io Pro's offline desktop app and your workflow depends on it
- You rely on its VisionLog colour space or its specific film stocks
Use Luttie when:
- You want film emulation in a browser tab, with nothing to install
- You need a .cube LUT for DaVinci Resolve, Premiere Pro, Final Cut Pro or CapCut desktop
- You shoot log (S-Log3, C-Log3, N-Log, Apple Log, DJI D-Log) or RAW and want to grade it in the browser
- You never had Color.io, or you've lost access to it
