I previously wrote about cast shadows. Cast shadows in paintings usually have some blue because of the sky’s colour. Cast shadows can provide viewers with information. We can see the direction of the light. We also know the shape of the object casting the shadow. We can tell the time of day; at noon cast shadows are short and have sharper edges. We can tell the manner of the place of the cast shadow. The cast shadow gets lighter and bluer as it moves away from the object casting the shadow for it gets bluer from the sky. The cast shadow is usually darker close to the object and lighter as it moves away from the object. When I am out walking, I examine the details of cast shadows. I also do this when I am inside.
