Just to add some cool etymology to your reply: the word silhouette comes from a type of affordable portrait made by quickly painting or cutting out a persons profile in black paper.

The word silhouette is derived from the name of Étienne de Silhouette, a French finance minister who, in 1759, was forced by France’s credit crisis during the Seven Years’ War to impose severe economic demands upon the French people, particularly the wealthy.[3] Because of de Silhouette’s austere economies, his name became synonymous with anything done or made cheaply and so with these outline portraits.[4][5] Prior to the advent of photography, silhouette profiles cut from black card were the cheapest way of recording a person’s appearance.[6][7]
