The Elements of Art...

An easy way to think of the Elements of Art is as the ingredients that an artist uses to create visual art. Similar to the ingredients used in baking a cake or cooking a chicken, the elements of art are used to create a sculpture, a painting, a website or even a comic strip. An artist, of course, does not need to use every element for every piece of art, same as a baker or a cook doesn't need to use all ingredients available to them for every meal. As artist we pick and choose what will fit our artistic needs.
If the Elements of Art are the ingredients...what are the Principles of design?
