The Honest Color.io Alternative for Video Editors | Leumos AI

Color.io is Picture Instruments' look-development tool — strongest for LUT creators, photographers, and hybrid shooters who grade frame-by-frame using its AI Match feature. Leumos AI is the alternative built for solo videographers who need shot-by-shot grading on a video timeline, with AI Scene Cut Detection, Reference Image Grading, and browser-based uploads up to 2GB on Pro.

I'm Pravit. DaVinci Resolve Certified colourist, BFA in cinematography, and I've graded ad work for Puma and WHSmith, indie features that hit festivals, plus enough music videos to ruin my Spotify recommendations. Before I started building Leumos AI, I tested every consumer-facing color tool I could lay hands on. Color.io was one of the more interesting ones and one I'd still recommend — to the right person. The problem is that if you're a solo videographer cutting wedding films, YouTube docs, brand reels, or short-form for clients, you're probably not that person. Here's the honest breakdown.

Where color.io wins

Picture Instruments has been making color and tone-mapping tools for years, and that pedigree shows. The Hollywood-trained LUTs are genuinely useful starting points if you want a recognizable filmic look rather than yet another teal-and-orange preset. The AI Match feature is impressive on stills and isolated frames: drop a reference image, hit match, get a defensible look in seconds. For a photographer extending into motion, or a hybrid shooter who treats every project as look-dev before they take it into Lightroom or Resolve, the workflow makes sense.

A few more things color.io does well:

• Offline iPhone use. It runs on iOS without a connection, which is rare. If you're grading on a plane or on a shoot day in a basement, that matters.
• One-time-feeling pricing. Pro is $99/year — clearly aimed at solo creatives who don't want a $39/month bite.
• LUT export. If your real workflow is "design a LUT, take it into Premiere or Resolve," color.io is built for exactly that.
• A free tier that actually lets you do work. You can grade and export without paying, with limits.

Take the strengths seriously. If your output is one beautiful frame at a time, or a LUT file, color.io is a sharp tool.

The color.io trade-off most filmmakers run into

Here's the workflow that breaks. You're a solo videographer. You shot a wedding on an FX3 in S-Log3, you have 47 clips across ceremony, reception, golden-hour couple portraits, and indoor dance floor. Your timeline is 8 minutes and the client wants it Friday.

In color.io, every clip is essentially its own image you grade. You can pull a reference frame, you can match, you can copy settings — but the tool's mental model is a frame, not a sequence. There's no scene-cut awareness, no concept of "match the next 12 clips to this hero shot because they're the same coverage." The dance floor clips, lit by RGB DJ lights, will need their own matched look. The portraits, lit by sunset, need theirs. The ceremony footage, mixed window light, needs a third. In color.io you do that work clip by clip, eyeballing each one against your reference, exporting each one out.

It works. It's just slow, and it forces you into a photographer's brain — one frame, one decision, one export — at the exact moment you need a video editor's brain: one timeline, one look, propagate it, fix outliers.

The other quiet cost is file size and codec handling. Long-form video, BRAW, ProRes RAW, big 10-bit H.265 out of a Sony FX3 — that's not where color.io is sharpest. It's at home with image files and short clips, which is honest to what it was designed for.

How Leumos AI handles this differently

I'm building Leumos AI because I kept watching working videographers — not colorists, videographers — lose entire afternoons to shot-by-shot equalization that should take fifteen minutes. The tool is built around the timeline, not the frame.

Here's the workflow Leumos AI is being designed for. You upload your edit or your raw clips (up to 2GB per file on Pro, 1GB on Creator). The AI Scene Cut Detection splits your video into shots automatically. If it misses a cut or splits one it shouldn't, you correct it with the Manual Cut Tool — no node tree, no timeline gymnastics.

From there, you have three ways to set the look:

• Reference Image Grading: drop in a still — a Roger Deakins frame, a Khalik Allah portrait, a screengrab from a music video you love — and grade your hero shot to it.
• Preset LUT Library: pick a starting LUT if you'd rather work top-down.
• Manual Primaries: lift/gamma/gain when you want the AI out of the way.

Then the part that matters for solo videographers: Match All. One click and the look propagates across every shot in the sequence, with the AI handling exposure and color differences shot-by-shot. The Input Color Space LUT means your S-Log3, C-Log3, or BRAW is interpreted correctly before any creative grade lands on top — so you're not fighting flat footage while you try to set a look.

It runs in the browser. No install, no GPU minimum, no node soup. You will be able to open it on a borrowed laptop at a client's office and finish a grade.

Important honesty: Leumos AI is not live yet. I'm building it now. The MVP launches in roughly 30 days. The features above are what's shipping at launch — not a roadmap, not "coming soon" promises layered on a press release.

Which one should YOU pick?

Pick honestly based on what you actually shoot:

• You design LUTs as your output → color.io. Its whole shape is built for this. Leumos AI doesn't export LUT files at launch.
• You're a photographer extending into motion → color.io. The frame-first UX matches how you already think.
• You grade on iPhone offline → color.io. Leumos AI is browser-based and needs a connection.
• You're a solo videographer with timelines (weddings, YouTube, brand work, docs) → Leumos AI. AI Scene Cut Detection plus Match All is the whole point.
• You shoot S-Log3, C-Log3, BRAW and want one look across a full sequence → Leumos AI. Input color-space handling plus Match All is faster than per-clip matching.
• You want the cheapest possible entry and a low ceiling → color.io's free tier. If you outgrow it, Leumos AI's Creator tier at $15/mo is the next honest step up.

There's no shame in using both. A lot of working colorists own three or four tools because each one is sharpest at one thing.

Price comparison

Tool	Free tier	Paid tier
color.io	Yes, with limits	Pro $99/year
Leumos AI	$0 — 2 uploads/day, 400MB	Creator $15/mo (8 uploads/day, 1GB, 14-day storage) · Pro $39/mo (20 uploads/day, 2GB, 30-day storage)

color.io's $99/year reads cheaper on paper, and it is — if its workflow fits your work. Leumos AI's pricing is monthly because the tool is designed to be used during projects: pay for the month you're delivering wedding films, pause when you're not. The first 500 early-access signups get 50% off the first year on any paid tier.

Frequently asked questions

Is color.io better than Leumos AI for grading on iPhone?

Yes — color.io runs natively on iOS and works offline, which Leumos AI doesn't. If your real workflow is grading on a phone in the field, on a flight, or anywhere without reliable internet, color.io is the right choice. Leumos AI is browser-based and needs a connection. The trade-off is what each tool is optimized for: color.io is shaped around single-frame or short-clip work that fits a mobile-grading session, while Leumos AI is built for full video timelines with multiple shots that need to match each other.

Does Leumos AI export LUTs the way color.io does?

Not at launch. The Leumos AI MVP ships with Reference Image Grading, AI Scene Cut Detection, Match All, a Preset LUT Library, Input Color Space LUT, Manual Primaries, Manual Cut Tool, and export — but it doesn't export LUT files as a deliverable. If you're a LUT designer whose final product is a .cube file someone else loads into Premiere or Resolve, color.io is the better fit today. Leumos AI exports graded video. If LUT export comes later it'll be a deliberate add, not a launch-day promise.

Can I grade BRAW or ProRes RAW footage in Leumos AI?

Yes, Leumos AI will support common video formats including BRAW and ProRes RAW within the 2GB upload limit on the Pro tier. The Input Color Space LUT handles log profiles — S-Log3 from an FX3, C-Log3 from Canon, V-Log, N-Log — so your footage is interpreted correctly before any creative grade lands on top. For files over 2GB you'd need to pre-transcode, the same as in any browser-based tool. color.io can handle raw image formats well but isn't where I'd take a 90-minute wedding edit.

Why is Leumos AI browser-based instead of a desktop app like color.io?

Two reasons. First, install footprint: a lot of solo videographers work on borrowed laptops, client machines, or older hardware that won't run a heavyweight desktop app well. Browser-based means you open a tab and grade. Second, my background is that I've watched too many filmmakers lose a day to driver issues, GPU mismatches, and update loops. Browser deployment removes that surface entirely. The cost is that you need a connection — fair trade for solo videographers who deliver from coffee shops, edit suites, and home offices rather than from a basement at 30,000 feet.

When is Leumos AI launching, and will there be a free plan?

Leumos AI launches in roughly 30 days from this post. There will be a free tier at $0 with 2 uploads per day and a 400MB file limit — enough to test AI Scene Cut Detection and Match All on real footage before you commit. The first 500 early-access signups get 50% off the first year on Creator ($15/mo) or Pro ($39/mo). I'm holding the discount to a genuine first-500 so the people who back this early actually get rewarded for it, not the next 5,000 who show up after launch.
