Colour Theory for Creators, Without the Jargon

You do not need the vocabulary to use the ideas. Colour grading is mostly one move repeated: push shadows one way, highlights the opposite way, and leave skin alone. Here is why that works and what your options are beyond the obvious pair.

The one idea that matters: separation

Human eyes read depth from colour difference. When shadows sit cool and highlights sit warm, the frame separates into layers and feels three-dimensional. That is the whole trick behind most cinematic grades: not saturation, separation.

Why teal and orange became the default

Skin is orange. Put anything near teal behind it and the subject pops, because teal is roughly opposite orange on the wheel. It became a cliche because it works on the most common subject in the world, people.

• Shadows: hue 200 to 215, saturation 12 to 20
• Highlights: hue 35 to 45, saturation 8 to 15
• Keep total saturation low, the effect should be felt

Three alternatives that work as well

Opposites are not limited to one pair. Each of these gives the same separation with a different emotional read, and all three are less used, which makes your work look less templated.

• Blue and amber: colder, more nocturnal than teal and orange
• Green and magenta: unsettling, editorial, good for fashion
• Purple and yellow: warm nostalgia, works on film-style edits

Protecting skin while you grade

Every grade eventually lands on someone face. In the colour mix panel, pull orange saturation down slightly and orange luminance up. This single step is the difference between a graded portrait and a sunburnt one.

Tip. Zoom to 100% on a face before and after grading. If the hue shifted, back off the orange channel, not the whole grade.

Knowing when to stop

Look away from the screen for ten seconds, then look back. If the colour is the first thing you notice instead of the subject, you have gone too far. Good grading is almost invisible until you see the original next to it.
