Primaries
Why this lesson
Section titled “Why this lesson”You’ve felt the four controls (1.1) and you can now read the scopes (1.2). This lesson is where those meet: the primary tools — the wheels and bars that move the whole image at once. “Primary” just means global: whatever you do here lands on every pixel, unlike the targeted work that comes later. This is 90% of the job. A shot that’s exposed right, neutral, and contrasty — done entirely with primaries — is already better than most footage on the internet. The trap beginners fall into is grabbing every tool at once and pushing until it “looks cool.” Instead you’ll learn what each primary control actually pulls on, in what order, and how to confirm it on the scopes rather than the screen.
The explainer
Section titled “The explainer”Resolve gives you the same primary controls in two shapes: wheels (four color wheels with a ring and a brightness slider each) and bars (the same values as vertical sliders you can nudge one channel at a time). They do identical things — pick whichever you read faster. The bars are better when you want to move one color channel; the wheels are better for feeling color and brightness together. Here’s what each control pulls on.
Lift, gamma, gain — the three tonal zones. Think of the brightness range as three overlapping regions. Lift pulls on the shadows (the dark end), gamma pulls on the mid-tones (the middle — where faces live), and gain pulls on the highlights (the bright end). Each wheel’s ring tints that zone’s color; each wheel’s slider moves that zone’s brightness. Drop lift and your blacks sink; raise gain and your highlights climb. On the waveform you’ll see the bottom, middle, or top of the trace respond depending on which one you touch. Splitting your work across these three is how you shape a tonal range instead of just making the whole thing brighter or darker.
Offset — the whole image at once. Offset is the beginner’s best friend, and it’s why Mostyn tells newcomers to start there. The offset slider raises or lowers every tone together — the entire waveform slides up or down as one — and the offset ring pushes the whole image’s color one way. It’s the fastest route to “brighter and warmer” or “darker and cooler” without fiddling three wheels. Many colorists set their overall exposure and remove the gross color cast with offset first, then reach for lift/gamma/gain to fine-tune the zones.
Contrast and pivot — the punch, and where it pushes from. Contrast increases the distance between the darkest and lightest parts of the image, pushing the top of the waveform up and the bottom down at the same time. It reveals mid-tone detail and gives a flat image life. But contrast pivots around a middle point, and if that point is wrong the whole image ends up too dark or too light. That’s what pivot is for: it sets the brightness level that contrast rotates around. Add contrast, and if the shot goes muddy, raise the pivot to rebalance — the punch stays, the overall brightness comes back.
Primary vs. creative. Everything above is correction — making the image technically right: correct exposure, neutral color, sensible contrast. A creative grade is what you add on top once it’s correct: a warm sunset feel, a cold thriller cast, a bleached look. Both often use the very same primary wheels, so the difference isn’t the tool — it’s the intent. Correct first, always. A creative look built on an uncorrected image just amplifies the problems you never fixed. In Level 1 you stay almost entirely in correction; the creative layer becomes its own discipline in Level 2.
The order to work in, every time: offset to set overall exposure and kill the obvious cast → lift/gamma/gain to shape the zones → contrast and pivot for punch → a touch of saturation last. Confirm each move on the waveform and parade, not on your maybe-lying screen.
- On the Color page, grab a flat-looking clip and open the Primaries palette with the scopes visible (waveform + parade).
- Start on offset: set overall brightness with the slider so the mid-tones sit sensibly, then use the ring to pull out the obvious color cast until the parade columns roughly line up.
- Move to lift / gamma / gain: drop lift to set your blacks, lift gain to set your whites, nudge gamma so the face sits right. Watch the bottom, top and middle of the waveform respond.
- Add contrast. When it goes too dark or too bright, fix it with pivot — don’t undo the contrast.
- Add a small amount of saturation to finish. Toggle the node off/on (click its number) to compare against the original.
- Now do the same shot again using the bars instead of the wheels, to feel the difference.
Terms introduced
Section titled “Terms introduced”Check yourself
You want to shift the mood of the whole shot — shadows, mids and highlights together — up or down in one move. Which control?
Lift, gamma and gain each pull on a different part of the tonal range. Which is which?
You add contrast and the image gets punchier but now looks too dark overall. Which control rebalances it without undoing the contrast?
What is the difference between a primary correction and a creative grade?
You can move on when you can… take a flat clip and, using only primaries in order (offset → lift/gamma/gain → contrast/pivot → saturation), make it correct — and name what each control changed and where you saw it on the scopes.

Section titled “Go deeper”Blackmagic Introduction to Color — primaries and contrast/pivot: the official hands-on version of exactly this workflow. In this segment the presenter reads the scopes, works the offset and lift/gamma/gain wheels, then demonstrates contrast and pivot the moment the image goes too dark — the clearest demo of the pivot fix anywhere.
