What Does a Colorist Do?

The colorist is the last person to make a creative decision about the picture. Everything after them is delivery.

What does a colorist do?

The colorist grades the film: adjusting exposure, contrast, saturation and colour shot by shot, matching shots to each other so a scene reads as one continuous place and time, and then shaping the whole thing into the look the film is released with.

The matching is the part outsiders underestimate. A dialogue scene shot across a full day changes light continuously — the sun moves, the sky clouds, the gaffer relights for the reverse. The audience must experience it as five uninterrupted minutes. Making that true is grading work, and it is most of the job before any stylistic look is applied at all.

Are there two kinds of colorist?

Yes, and job listings rarely distinguish them.

Dailies is the less visible of the two and in some ways the harder deadline: an entire unit is waiting to see whether yesterday worked, and the answer has to be there before the morning call. Finishing is the one people mean when they say colorist, and it is a room, a director, a cinematographer and a lot of hours on individual shots.

Who represents colorists?

In the United States, post-production crafts sit with the Motion Picture Editors Guild, IATSE Local 700, which profiles working colorists among its members. Local 700 took its current shape in 1998, when IATSE consolidated post-production jurisdiction into it — including post-production sound mixers, recordists and engineers ceded from Local 695 — and it is only the second IATSE local granted a national rather than a regional charter.

Worth saying honestly: colour is much less uniformly unionised than camera or electric. A large share of colorists are staff at post facilities or independent operators working directly for producers, and outside the US the picture varies enormously. Do not assume the union structure that governs a gaffer's booking applies to a colorist's.

Why does what happens on set decide what the colorist can do?

Because a grade works with the information the camera recorded and nothing else.

Highlights clipped to white contain no detail to recover. Shadows crushed to black contain no detail to lift. A grade can rebalance, unify and shape what exists; it cannot manufacture what does not. Every colorist has had the conversation that begins "can you just bring back the window" and ends with the answer no.

This is exactly why the DIT exists. The DIT is monitoring the image on set, managing the LUT the director and DP are watching through, and flagging the moment an exposure decision is about to cost the grade an option. A production that treats the DIT as a data wrangler is a production that finds out about its exposure problems in a grading suite, which is the most expensive room in which to discover anything.

The LUT itself is a thread running through the whole pipeline: chosen in prep, applied on set so everyone is watching the intended look, carried through the offline edit, and finally used as the starting point of the real grade. When the look is decided in prep rather than discovered in the grade, the colorist spends their hours on craft instead of archaeology.

Where does the grade sit in the schedule?

After picture lock, and it is worth understanding why the order is not negotiable.

The grade is applied to the conformed cut — the locked edit rebuilt at full quality from the original camera media. Change the edit after that and shots that were graded no longer exist in the same form, which means the work is redone. This is the same reason a locked cut matters to sound and to visual effects, and the reason a director who reopens the edit late costs three departments at once.

How do you get hired as a colorist?

By reel, more than by credit. Colour is one of the few crafts where the work can be demonstrated directly rather than described: a before-and-after, a scene that matches, a look that holds across a whole film.

Which makes the usual problem sharper rather than softer. A credit list saying "Colorist" on nine titles conveys nothing, while thirty seconds of the actual work conveys everything. If your work lives in projects a producer cannot easily watch, the strongest argument you have is one they never see — the case for keeping a public Crew Card with the work attached, and for building a showreel that leads with the images rather than the titles.
