Color labels for culling: a system that survives

Workflow & Gear

Almost every photographer has tried color labels and quietly given up on them. The colors are fine. The problem is that most systems ask labels to record quality, which stars and flags already do better. Here is a five color system built around actions instead, how it pairs with the marks you already use, and the settings that make it survive a real shoot.

01 · WHY THEY FAIL

Why most label systems die by shoot three

Color labels are the most abandoned feature in photo software. Not because they are badly built, but because nothing in the app forces them to mean anything. Stars have an obvious ladder. Flags have two states and one question. Labels are five buttons with no instructions, so on shoot one they mean whatever you decided that evening, and by shoot nine they mean nothing at all.

The pattern is always the same. First job, red is "needs a crop". Second job, red drifts to "not sure". Third job, half the shoot is yellow and you could not say why. By the fourth you stop using labels, and the ones already in the catalog quietly rot: a color on a thumbnail that no longer maps to any action.

That is a system problem, not a discipline problem, and it has a specific cause. Most photographers try to use labels to record how good a photo is. Quality already has two homes, and the argument over which of those two you should be using is the stars versus flags question. Labels are for something else entirely, and once you see what, the system stops collapsing.

02 · THE ONE RULE

A label names an action, not a grade

Here is the rule the whole article hangs on. A color label names what has to happen to a photo next. It does not say how good the photo is.

Quality is a judgment. An action is a job. Judgments drift with your mood, the hour and the last hundred frames you looked at. Jobs do not: either a frame needs a background fix or it does not, either the couple asked for it or they did not. That is why an action based label survives a season and a quality based one does not.

Once you accept that, the three marking systems stop competing and start dividing the work.

MarkingThe question it answersWhat it gets applied toWhat it feeds
FlagsIs this in or out?Every frame on the cardThe pick list
StarsWhat is this pick for?Only the picksAlbum, sneak peek, portfolio
Color labelsWhat has to happen to it?Only the picks that need workYour to do queue

Read the third column carefully. Flags touch everything, stars touch a few hundred, labels touch a few dozen. If you are labeling hundreds of frames per shoot, you are using labels as a second star scale, and that is the exact move that kills the system.

03 · THE SYSTEM

Five colors, five jobs

Five colors, five jobs, one sentence each. Steal this or write your own, but write it down and keep it for a year.

ColorKeyWhat it meansWho acts on it, and when
Red6Needs work before it can ship: a crop, a blend, a distraction to clone outYou, at the editing stage
Yellow7Named request: someone asked for this frame, so it goes in the gallery whatever else happensYou, at the final delivery check
Green8Cleared: approved by whoever had to approve it, including a second shooter frame you have checkedYou or your team, once
Blue9Goes out early: sneak peek, blog post, socialsYou, this week
Purpleno keyOn hold. You cannot decide, and you refuse to spend another minute on it tonightYou, tomorrow, with coffee

Two things make this hold up where a color coded quality scale does not. Every row names a person and a moment, so a label is a promise with a deadline rather than a feeling. And every row can be filtered into a work queue: red is your retouch list, blue is your Monday morning post, purple is the pile you were sensible enough not to settle at midnight.

Purple is the useful accident

Adobe's published shortcut list gives keys to red, yellow, green and blue only. Purple has no keystroke: you apply it from the Photo menu, under Set Color Label. That friction is worth keeping. The hardest label to reach is exactly where the "I do not know" pile belongs, because a decision you defer should cost you a small effort, not the same reflex as every other frame.

04 · MAKE IT STICK

The settings that make it survive

A label system survives contact with a real shoot when the meanings live in the file rather than in your memory. Three settings do most of that work.

Name the colors. In Lightroom Classic, go to Metadata, then Color Label Set, then Edit. Adobe is explicit about what naming buys you: the name "is then added to the photo's metadata when you apply the label." A color is a color, but "needs retouch" is an instruction, and it is the instruction that gets written down. This takes two minutes once. See Adobe's own page on flagging, labeling and rating for the full menu path.

Use one set everywhere. Because the label writes a name into the file, two catalogs with two different label sets will not agree with each other. Pick one set, apply it to every catalog you own, and give your second shooter the same one before the day rather than after it. Standards agreed in advance are the whole argument in our guide to second shooter culling standards.

Learn four keys. 6, 7, 8 and 9 apply red, yellow, green and blue. Hold Shift with any of them and the label is applied and you move to the next photo in one press. Both are on Adobe's shortcut list, on Mac and Windows alike, along with the filter keys that turn labels back into a work queue. The full set with both platforms is in our Lightroom keyboard shortcuts cheat sheet.

One thing worth updating if you learned this years ago: flags used to be a catalog only marking, which is why photographers were told to keep the durable meaning in labels and ratings. Adobe changed that. As of Lightroom Classic 13.2, flag states are saved to XMP and are visible outside the catalog. Flags travel now too, so the reason to keep labels for actions is not portability, it is clarity.

05 · THE PASS ORDER

When labels go on, and when they must not

The order matters more than the colors. Labels applied at the wrong moment are what turns a two hour cull into an evening.

  1. In or out, flags only. One question, one keystroke, no colors. Do not stop to think about what a frame will need later, because you do not yet know if it survives.
  2. Filter to the picks. Everything after this point happens on the shortlist, which is a fraction of the card.
  3. Stars for purpose. A quick pass over the picks marking what each one is for, if you use stars at all.
  4. Labels last, and sparingly. Now you go looking for the frames that need something to happen. Most picks need nothing and get no label. That is the correct result, not a failure to use the feature.
  5. Work the queue. Filter to red and do the fixes. Filter to blue and build the preview. Filter to purple when you are fresh. The label buttons on the Filmstrip do this in one click.

Notice that the first pass has no colors in it at all. Deciding "in or out" and "what does this need" at the same time is two jobs in one keystroke, and it is why people describe culling as exhausting rather than merely long. The wider version of this staging is in our wedding culling workflow, and the criteria that drive that first pass are worth settling separately: build your culling criteria.

07 · THE LIMITS

What labels are not for

Labels are for the job in front of you. They are a queue for this shoot, cleared when the gallery ships. For anything that has to hold up over years, use something built to last: a collection for the album shortlist or the portfolio, keywords for anything you will search for by subject in three years. Labels rot because they are meant to be temporary. That is a feature, as long as you do not ask them to be a filing system.

It is also worth saying that all of this marking is downstream of the slow part. Industry norms put a wedding day at 2,000 to 4,000 RAW frames and 400 to 800 delivered images. The color labels land on a few dozen of those. The hours go on the first pass, the one where you look at every frame and decide whether it lives in the gallery, and no label scheme has ever made that pass shorter.

That is the pass Kepla is being built to take off you. Kepla checks every frame against clear criteria and hands you a shortlist to approve, and it never deletes, moves or renames a single file: every original stays exactly where it is, and anything not picked is one tap away. You approve on your iPhone or iPad on the way home, and open the same shoot on the Mac when a frame needs a proper look. Then Lightroom gets a shortlist instead of a card, and your labels go on the handful of photos that actually need something to happen.

The picking app is still being built. The booking page is live today and free while we build, and if you want a printable version of the pass order above, it is folded into our photo culling checklist.

08 · COMMON QUESTIONS

FAQ

What should each color label mean when culling?

Give each color an action rather than a quality level. A workable set is red for frames that need work before they ship, yellow for photos someone specifically asked for, green for anything cleared or approved, blue for images going out early as a sneak peek, and purple for the ones you cannot decide on tonight. Write your five in one sentence and keep them for a full year.

Should I use color labels or star ratings for culling?

Both, for different jobs. Flags settle whether a photo is in or out, stars say what a pick is for, and color labels say what still has to happen to it before it ships. Ratings and labels are not competing scales. If you find yourself labeling hundreds of frames per shoot, you are using color as a second star system and it will stop making sense within a month.

What are the keyboard shortcuts for color labels in Lightroom?

In Lightroom Classic, 6 applies red, 7 yellow, 8 green and 9 blue, on both Mac and Windows. Hold Shift with any of those and Lightroom applies the label and moves to the next photo in one press. Purple has no key on Adobe's published list, so you apply it from the Photo menu under Set Color Label, which makes it a useful home for undecided frames.

Do color labels travel between Lightroom and other programs?

The label writes a name into the photo's metadata rather than a color, which is why Lightroom lets you name your labels under Metadata, Color Label Set, Edit. If another catalog or program uses a different set of names, the two will not line up. Use one label set everywhere, and agree it with a second shooter before the shoot rather than after.

How many photos should get a color label?

Far fewer than you think. Labels go on picks only, and only on picks that need something to happen next. On a typical wedding that might be a few dozen frames out of several hundred delivered images. If most of your gallery is colored, the labels have stopped carrying information and are just decoration on the thumbnails.
