Grade a clip with two colors: one for the shadows, one for the highlights. The default teal shadows and amber highlights give the complementary look of a lot of film and streaming work, since skin tones sit in the warm half.
Colors and saturation
Choose Shadow Color and Highlight Color to set the grade. The step applies each at 35% saturation, which keeps the tint subtle; Mix blends the whole grade back toward the original.
Balance
Balance moves the crossover point. A night scene with mostly dark tones takes almost all the shadow color; shift the balance toward the shadows so the highlight color reaches faces and lights.
A grade across cuts
The same curve is applied to every frame, so the grade holds across cuts and camera changes. Pair it with the matte video effect for a faded film grade.
