Colour grading is the stage at the end of the edit where the colour, contrast and brightness of every shot are set, so the film looks the way it's meant to feel. It's how a director makes one world feel sickly and another feel cold, or makes a summer field look like an old postcard. Done well, you never notice it. You just feel it.
I covered the basics briefly in what cinematography means. This goes further: what a grade is actually doing, why it isn't the same as fixing the colour, and a few famous films where the colour was doing a lot more of the storytelling than most people realise.
What's the difference between colour correction and colour grading?
Correction is technical. Grading is creative. They happen in that order, and people mix the two words up all the time.
Correction makes the footage accurate and consistent. White balance so a white wall reads white. Exposure evened out so one shot isn't a stop darker than the next. Two cameras matched so a cut between them doesn't jump. The aim is a neutral, honest starting point where every shot in a scene looks like it was filmed in the same place at the same time.
Grading is what you do with that neutral image. Pushing the shadows cooler, warming the highlights, pulling saturation out of everything except one colour, crushing the blacks or lifting them so the image goes soft and milky.
On a documentary shoot you can't control most of what's in front of you, so correction does a lot of heavy lifting. A morning interview by a window and an afternoon shot under strip lights need to sit next to each other without the viewer feeling the join. There's more on why mixed light causes so much trouble in interview lighting explained simply.
How does colour create mood?
Mostly through association. We've spent our whole lives seeing warm light at sunset, by a fire, in a kitchen at night. Cool, blue light is overcast mornings, hospitals and the hour before dawn. A grade borrows those associations and points them at a scene.
A few of the levers a colourist actually pulls:
- Temperature. Warmer reads as comfortable, nostalgic or intimate. Cooler reads as detached, clinical or lonely.
- Saturation. Rich colour feels alive and heightened. Muted colour feels serious, tired or documentary-real.
- Contrast. Deep blacks and bright highlights feel punchy and dramatic. Lower contrast feels gentle and soft.
- Separation. Different colours in the shadows and the highlights, which is where most stylised looks live.
None of these mean anything on their own. Cool and desaturated can feel calm in one film and grim in another. The grade only works when it agrees with what the story's already saying.
Why is The Matrix green?
Because the computers made it. The Matrix is probably the best-known example of colour being used as a map. Scenes inside the simulation carry a green tint. Scenes in the real world, aboard the ship and in the ruins, are cool and blue, with almost no green in them at all.
The film's cinematographer, Bill Pope, explained the thinking in an interview for the film's official website. The Matrix is a decaying world created by machines, so it got a green hue, and it was meant to make you feel slightly sick. The real world got a colder, bluer look, because in that future the sun's been blotted out and there's no natural warmth left.
Once you've noticed it, you always know where you are.
What is the teal and orange look?
It's the look of a huge number of action films from the 2000s onwards: skin pushed warm towards orange, and shadows, skies and backgrounds pushed cool towards teal. Watch almost any big blockbuster trailer and you'll see it.
It caught on for a sound reason. Orange and teal sit roughly opposite each other on the colour wheel, so they contrast strongly, and most skin tones fall in the orange range. As Adobe's guide to the look puts it, pushing blues into the shadows helps those skin tones stand out. It also mimics golden hour, warm sun on a face against a blue sky, which people already find beautiful.
The trouble is that it got used everywhere, whether the story asked for it or not. When every film has the same look, the look stops meaning anything, and it starts to feel like a preset rather than a decision.
Which other films use colour to tell the story?
O Brother, Where Art Thou?
The Coen brothers wanted a dry, dusty, faded postcard look. The problem was that they were shooting in Mississippi in summer, where everything was lush and green. Roger Deakins, the cinematographer, told Filmmaker Magazine that they didn't want anything to be green, and couldn't find a way to turn the greens into browns and yellows with traditional film processing. So they scanned the film and graded it digitally. It's widely credited as the first Hollywood feature to be colour graded digitally from start to finish, which makes it a quiet turning point.
Mad Max: Fury Road
Fury Road went the opposite way to most post-apocalyptic films. Its colourist, Eric Whipp, told FilmLight that George Miller had noticed thirty years of the genre using the same desaturated, bleached look, and was adamant this one should be saturated, sharp and graphic. Whipp built rich skies against warm sand and characters, and the night scenes were shot in bright sun, then darkened and pushed blue in the grade. He worked on it for about a year.
Mad Max: Fury Road, official trailerThe official trailer above shows that saturated orange and blue at full volume. Miller has since said he thinks the black and white version, released as the Black & Chrome edition, is the best version of the film, as /Film reported. Same footage, completely different grade, and the director's favourite.
Same footage, completely different grade, and a different film.
What is a LUT, and is it the same as a grade?
A LUT, short for look-up table, is a file that maps one set of colours to another. Feed it a pixel of one colour and it hands back a different one. That's all it is.
There are two kinds worth knowing about. A technical LUT converts footage from one colour space to another, most often turning the flat, grey log footage a cinema camera records into a normal-looking image. A creative LUT applies a look, like a filter on your phone.
Treat a LUT as a starting point. It treats every shot exactly the same way, and no two shots are exactly the same. A look built for a bright exterior can turn a dim interior muddy and push skin somewhere strange. A proper grade still goes shot by shot, adjusting each one so the look holds across the whole film.
Why do skin tones matter so much in a grade?
Because people notice faces before anything else, and they're very good at knowing when one looks wrong. A wall can go teal and nobody minds. A face goes grey, green or orange and the viewer feels something's off straight away, even if they can't say what.
Colourists usually protect skin first, isolating it so it stays natural while the rest of the image is pushed around it. There's a scope for this called a vectorscope, which has a line marking roughly where healthy skin of every complexion tends to sit. The real skill is lighting and grading darker and lighter skin in the same frame so both look right, which was handled badly for a long time and still is on plenty of corporate video.
What does grading mean for a brand film?
Most brand films don't need a dramatic look. They need to look like the place on a good day and to feel consistent from start to finish. A workshop should feel warm and lived in, a shop should look like the shop, and the founder should look like themselves. If the grade gets noticed, it's probably gone too far.
Where it does earn its keep is in mood and in continuity. A documentary is shot over different days, rooms and weather, and the grade is what makes it feel like one film. It can also carry a story, the way The Matrix does.
On our films the grade is done by a specialist colourist, after the edit is locked, because it's one of the clearest differences between a film that looks expensive and one that looks like a video. You can see how that fits into the rest of the process on the films page, and if you're working out what a film should cost, the film budget calculator is a decent place to start.
