Lighting should describe physical sources and transitions, not abstract beauty. A useful lighting prompt tells the model where the light comes from, its color temperature, how shadows behave, what atmosphere catches the light, and whether the light changes during the clip.

Load [ref:color-pipeline-aces] when the user asks for ACES, HDR/SDR, show look, grade, LUT, CDL, product color, or professional color handoff. Load [ref:directing-engine] for lighting as emotion - ratio, key direction, color temperature, motivation, and light that changes with the dramatic turn - so the light expresses the scene's intention rather than just illuminating it.

Intent

When users say mood words, they are almost always asking for light. This skill's purpose is to take "cozy," "lonely," or "electric" and answer with a sun, a lamp, or a window - because that is where feeling physically lives in a frame. Give them their emotion back as a light source they can point to.

Lighting Contract

State: key source, direction, color temperature, atmosphere, shadow behavior, reflective behavior, and any transition.

Source Selection

Use practical lamps for interiors, intimacy, and visible motivation. Use window light for naturalism and food or lifestyle scenes. Use rim light when separation matters. Use hard light for noir, harsh sun, or graphic shadows. Use soft light for beauty, skin, product polish, and children or family scenes. Use moving light when the scene needs a visible change.

Color and Atmosphere

Name color temperature only when it matters: warm tungsten, cool moonlight, green fluorescent, sodium streetlight, neutral overcast daylight. Add atmosphere sparingly: mist, dust, rain streaks, smoke, or condensation should interact with the light and the subject, not merely decorate the frame.

Failure Fixes

If an output looks flat, add a motivated key source, rim separation, and one material-specific highlight. If it looks over-processed, remove broad style claims and specify softer contrast. If flicker or lighting jumps appear, make the light source stable and remove competing transitions.

Sequence State

When sequence state is present, inherit persistent practical sources, key direction, lighting phase, current clip scope, continuity locks, exact reference tags, and reserved future beats. Do not reset day/night, practical lamps, or weather light unless the transition or allowed changes explicitly permit it.

Output Contract

Return a compact lighting block, a transition note if needed, and one prompt-ready integrated sentence.
