Johannes Itten distinguished between seven colour contrasts based on the colours of his colour wheel that describe varying subjective effects that different colour contrasts and combinations have on the viewer. A systematical analysis of an excerpt regarding its colour contrasts can be very useful for an artistic analysis of the colour composition. The color contrasts that are particularly relevant for film analysis are the contrast of pure hue, the complementary contrast, the light-dark contrast, the cool-warm contrast and the contrast of saturation.
