Color

Color theory in film is the practical knowledge of how hue, saturation and brightness interact and how filmmakers use palettes, contrasts and color changes to guide the eye and shape emotion.

A film's color palette is the limited set of colors that dominates its images — in sets, costumes, light and grade — chosen to give the film a coherent look and emotional temperature.

Complementary colors sit opposite each other on the color wheel — red/green, blue/orange, purple/yellow — and together create maximum color contrast; teal-and-orange is the best-known film version, setting warm skin against cool shadows.

Color symbolism uses colors as signs — red for love, danger or power, green for envy or sickness — but in film the meaning is set by context and repetition inside the story, not by a universal chart.

Selective color keeps one hue — or one object — in color while the rest of the frame is black-and-white or heavily desaturated, turning that object into the story's focal sign.

Technicolor is a family of color film processes; its three-strip version (from 1932 into the 1950s) split light onto three negatives and printed them by dye transfer, producing the saturated, jewel-like color of The Wizard of Oz and classic Hollywood musicals.

Sepia is a warm brown monochrome tint, originally from chemical toning of prints and now added in grading to evoke the past, memory or dusty heat.

A vectorscope is a video scope that plots every pixel by hue (angle) and saturation (distance from center), used in grading to check color balance, skin tones and legal saturation.

Saturation is how pure a color is — how far it sits from neutral grey; raising or draining it lets filmmakers build a vivid, heightened world or a muted, weary one.

A cool palette is dominated by blues, cyans and cold greens; it tends to read as distance, calm, loneliness, night or clinical control.

A warm palette is dominated by reds, oranges, ambers and yellows; it usually reads as intimacy, nostalgia, heat, comfort — or, pushed hard, danger and sickness.

A desaturated look drains color intensity across the frame without going fully black-and-white, giving a muted, cold, war-weary or documentary feel.

A monochromatic scheme builds the image from a single hue in different shades and tints — an all-red room, an all-green world — so meaning comes from lightness and texture rather than color contrast.

Colored lighting gives a scene its hue at the source — through gels, RGB LEDs, practicals and neon — either motivated by the world or openly expressive.
