Step-by-step: Block your colours with dominant hues
Blocking the shadow areas is the key to defining your colours later on, because shadows establish the boundaries between cold and warm colours. Here I show how the shadows in the scene can fall on the ground and other building elements. They also offer interesting possibilities for the composition. I pick two dominant colour values to set the basic palette of the scene. The best choices combine a cool colour with a warm one, because they enhance each other’s colour properties. You can achieve this using two Hue/Saturation layers: one for determining the colour for the shadow areas, the other one for the lit areas. Once the basic palette is fixed, I can continue refining the image by staying within my colour ranges for the shaded and the lit zones. The local colours of individual buildings and trees shouldn’t conflict with the basic colour palette defined in step two, otherwise there will be distracting colour noises in some areas.
