There are many examples of Studio Art in the External Art Links Library. For example, there is Rote Erde and this means "Red Earth" in German. Indeed, this is an example of a two-dimensional Studio Art Form via Artist Paul Klee from 1926 AD. In it, he used different variations of red and blue. Surely, these are examples of primary colors according to the Color Theory.
Likewise, there is "So Danish!" at Denmark's National Gallery of Architecture. Of course, this exemplifies three-dimensional art. In it, there are shapes like rectangles and squares. There are also neutral colors, such as brown; gray; white and even black in this Scientific Art Form.
