Today the term design is widely associated with the Applied arts as initiated by Raymond Loewy and teachings at the Bauhaus and Ulm School of Design (HfG Ulm) in Germany during the 20th Century.
The boundaries between art and design are blurred, largely due to a range of applications both for the term 'art' and the term 'design'. Applied arts has been used as an umbrella term to define fields of industrial design, graphic design, fashion design, etc. The term 'decorative arts' is a traditional term used in historical discourses to describe craft objects, and also sits within the umbrella of Applied arts. In graphic arts (2D image making that ranges from photography to illustration) the distinction is often made between fine art and commercial art, based on the context within which the work is produced and how it is traded.
To a degree, some methods for creating work, such as employing intuition, are shared across the disciplines within the Applied arts and Fine art. Mark Getlein suggests the principles of design are "almost instinctive", "built-in", "natural", and part of "our sense of 'rightness'." However, the intended application and context of the resulting works will vary greatly.
