Detailed Solution

The above statement is False.
A shadow is a dark shape that results from an opaque object obstructing the light rays coming from a source. Any object's shadow will always be black in colour. Since a shadow is created by an opaque object blocking all of the light's rays, there won't be any light there. As a result, we cannot see anything in that shape, and the shadow area will be black in colour. Therefore, regardless of the color of the object, the shadow's color is always black.
The correct statement would be object is colourful, the shadow is formed by blocking the incoming light. So, there is no relation between the color of the object and the shadow. Hence, the color of the shadow is always black irrespective of the color of the object. Here also, the color of the shadow of the green ball will be black.
