Color Space

Certain colors have an advancing or receding quality, based on how our eye has to adjust to see them. Warm colors such as red, orange or yellow seem to come forward while cool colors such as blue and green seem to recede slightly. In the atmosphere, distant objects appear bluish and the further away an object appears, the less colorful and distinct it becomes. Artists use this to give an illusion of depth, by using more neutral and grayish colors in the background
