'''Op art''', short for '''optical art''', is a style of [[visual arts|visual art]] that uses [[optical illusion]]s.<ref>Artspeak, Robert Atkins, {{ISBN|978-1-55859-127-1}}</ref>

Op artworks are [[Abstract art|abstract]], with many better-known pieces created in black and white. Typically, they give the viewer the impression of movement, hidden images, flashing and vibrating patterns, or swelling or warping.

[[Illusionism]], focused on the perception of extended space within a flat picture, is found from the earliest points of art history. However, the antecedents of op art, in terms of graphic effects and concern for exotic optical illusions, can be traced back to [[Neo-Impressionism]], [[Cubism]], [[Futurism]], [[Constructivism (art)|Constructivism]], and [[Dada]].<ref name="MoMA">{{cite web|url=http://www.moma.org/collection/theme.php?theme_id=10139|title=The Collection - MoMA|publisher=The Museum of Modern Art|access-date=November 5, 2017}}</ref> The [[Divisionist]]s, a group of Neo-Impressionist painters, attempted to increase the apparent [[luminosity]] of their paintings through recourse to optics and optical illusions.<ref name=Lee>Lee, Alan. "Seurat and Science." ''Art History'' 10 (June 1987): 203-24.</ref> [[László Moholy-Nagy]] produced photographic op art and taught the subject in the [[Bauhaus]]; one of his lessons consisted of making his students produce holes in cards and then photographing them.<ref>[https://www.theartstory.org/artist/moholy-nagy-laszlo/] László Moholy-Nagy</ref>

''[[Time (magazine)|Time]]'' magazine coined the term ''op art'' in 1964, in response to [[Julian Stanczak]]'s show ''Optical Paintings at the [[Martha Jackson Gallery]]'', to mean a form of [[abstract art]] (specifically non-objective art) that uses optical illusions.<ref>Jon Borgzinner. "Op Art", ''Time'', October 23, 1964.</ref><ref name="Visual-Arts-Cork.com">{{cite web|url=http://www.visual-arts-cork.com/history-of-art/op-art.htm |title=Op-Art: History, Characteristics |website=Visual-Arts-Cork.com |access-date=2019-12-15 |url-status=live |archive-url=https://web.archive.org/web/20240503044216/http://www.visual-arts-cork.com/history-of-art/op-art.htm |archive-date=2024-05-03}}</ref> Works now described as "op art" had been produced for several years before ''Time's'' 1964 article. For instance, [[Victor Vasarely]]'s painting ''Zebras'' (1938) is made up entirely of [[curvature|curvilinear]] black and white stripes not contained by contour lines. Consequently, the stripes appear to both meld into and burst forth from the surrounding background. Also, the early black and white "dazzle" panels that [[John McHale (artist)|John McHale]] installed at the ''[[This Is Tomorrow]]'' exhibit in 1956 and his ''Pandora'' series at the [[Institute of Contemporary Arts]] in 1962 demonstrate proto-op art tendencies. [[Martin Gardner]] featured op art and its relation to mathematics in his July 1965 [[Mathematical Games column]] in ''Scientific American''. In Italy, [[Franco Grignani]], who originally trained as an architect, became a leading force of graphic design where op art or [[kinetic art]] was central. His Woolmark logo (launched in Britain in 1964) is probably the most famous of all his designs.<ref>{{Cite web|url=https://eyeondesign.aiga.org/the-hypnotic-mind-bending-work-of-italian-designer-franco-grignani/|title=The Hypnotic, Mind-bending Work of Italian Designer Franco Grignani|date=2019-06-28|website=Eye on Design|language=en-US|access-date=2019-12-15}}</ref>

Op art perhaps more closely derives from the [[Constructivism (art)|constructivist]] practices of the [[Bauhaus]].<ref name="Visual-Arts-Cork.com" /> This German school, founded by [[Walter Gropius]], stressed the relationship of form and function within a framework of analysis and rationality. Students learned to focus on the overall design or entire composition to present unified works. Op art also stems from ''[[trompe-l'œil]]'' and [[anamorphosis]]. Links with [[psychological research]] have also been made, particularly with [[Gestalt psychology|Gestalt theory]] and [[psychophysiology]].<ref name="MoMA" /> When the Bauhaus was forced to close in 1933, many of its instructors fled to the United States. There, the movement took root in [[Chicago]] and eventually at the [[Black Mountain College]] in [[Asheville, North Carolina]], where [[Anni Albers|Anni]] and [[Josef Albers]] eventually taught.<ref>{{Cite web|url=https://www.theartstory.org/movement/black-mountain-college/|title=Black Mountain College Movement Overview|website=The Art Story|access-date=2019-12-15}}</ref>

<blockquote>Op artists thus managed to exploit various phenomena," writes [[Frank Popper]], "the after-image and consecutive movement; line interference; the effect of dazzle; ambiguous figures and reversible perspective; successive colour contrasts and chromatic vibration; and in three-dimensional works different viewpoints and the superimposition of elements in space.<ref name="MoMA" /></blockquote>

In 1955, for the exhibition ''Mouvements'' at the [[Denise René]] gallery in Paris, Victor Vasarely and [[Pontus Hulten]] promoted in their "Yellow manifesto" some new kinetic expressions based on optical and luminous phenomenon as well as painting illusionism. The expression ''[[Kinetic art#Apparent Movement and Op Art|kinetic art]]'' in this modern form first appeared at the [[Museum für Gestaltung]] of [[Zürich]] in 1960, and found its major developments in the 1960s. In most European countries, it generally includes the form of optical art that mainly makes use of [[optical illusion]]s, like op art, as well as art based on movement represented by [[Yacov Agam]], [[Carlos Cruz-Diez]], [[Jesús Rafael Soto]], [[Gregorio Vardanega]] or [[Nicolas Schöffer]]. From 1961 to 1968, the ''[[Groupe de Recherche d'Art Visuel]]'' (GRAV) founded by [[François Morellet]], [[Julio Le Parc]], [[Francisco Sobrino]], Horacio Garcia Rossi, [[Yvaral]], Joël Stein and [[Vera Molnár]] was a collective group of opto-kinetic artists that—according to its 1963 manifesto—appealed to the direct participation of the public with an influence on its behavior, notably through the use of interactive [[labyrinth]]s.

Some members of the group [[Nouvelle tendance]] (1961–1965) in Europe also were engaged in op art as Almir Mavignier and [[Gerhard von Graevenitz]], mainly with their serigraphics. They studied optical illusions. The term ''op'' irritated many of the artists labeled under it, specifically including Albers and Stanczak. They had discussed upon the birth of the term a better label, namely ''perceptual art''.<ref>Bertholf. "Julian Stanczak: Decades of Light" Yale Press</ref> From 1964, Arnold Schmidt ([[Arnold Alfred Schmidt]]) had several solo exhibitions of his large, black and white shaped optical paintings exhibited at the [[Terrain Gallery]] in New York.<ref>{{cite web|url=http://www.terraingallery.org/Some-History.html|title=A Brief History of the Terrain Gallery|publisher=TerrainGallery.org|access-date=November 5, 2017|archive-url=https://web.archive.org/web/20100403202917/http://www.terraingallery.org/Some-History.html|archive-date=April 3, 2010|url-status=dead}}</ref>

=== ''The Responsive Eye'' ===
In 1965, between February 23 and April 25, an exhibition called ''The Responsive Eye'', created by [[William C. Seitz]], was held at the [[Museum of Modern Art]] in New York City and toured to St. Louis, Seattle, Pasadena, and Baltimore.<ref>{{cite book|last1=Seitz|first1=William C.|title=The Responsive Eye (exhibition catalog)|date=1965|publisher=Museum of Modern Art|location=New York|url=http://ubu.com/historical/responsive/ResponsiveEyeMOMA1965.pdf|access-date=January 23, 2016|oclc=644787547}}</ref><ref>{{cite press release|date=February 25, 1965|title=The Responsive Eye|url=https://www.moma.org/momaorg/shared/pdfs/docs/press_archives/3439/releases/MOMA_1965_0015_14.pdf?2010|location= New York|publisher=Museum of Modern Art|access-date=January 23, 2016}}</ref> The works shown were wide-ranging, encompassing the minimalism of [[Frank Stella]] and [[Ellsworth Kelly]], the smooth plasticity of [[Alexander Liberman]], the collaborative efforts of the [[Anonima group]], alongside the well-known [[Wojciech Fangor]], [[Victor Vasarely]], [[Julian Stanczak]], [[Richard Anuszkiewicz]], [[Wen-Ying Tsai]], [[Bridget Riley]] and [[Getulio Alviani]]. The exhibition focused on the perceptual aspects of art, which result both from the illusion of movement and the interaction of color relationships.

The exhibition was a success with the public (visitor attendance was over 180,000),<ref>{{cite video |people=[[Gordon Hyatt]] (writer and producer), [[Mike Wallace]] (presenter)|date=1965|title=The Responsive Eye|url=https://www.youtube.com/watch?v=XSVQqJo0Pmk| archive-url=https://web.archive.org/web/20130103231508/http://www.youtube.com/watch?v=XSVQqJo0Pmk| archive-date=2013-01-03 | url-status=dead|medium=Television production|publisher=Columbia Broadcasting System, Inc.}} (Available on YouTube in three sections.)</ref> but less so with the critics.<ref>{{cite web|url=http://www.coolhunting.com/archives/2006/02/moma_1965_the_r.php|title=MoMA 1965: The Responsive Eye|publisher=CoolHunting.com|access-date=November 5, 2017|archive-url=https://web.archive.org/web/20090928015307/http://www.coolhunting.com/archives/2006/02/moma_1965_the_r.php|archive-date=September 28, 2009|url-status=dead}}</ref> Critics dismissed op art as portraying nothing more than ''[[trompe-l'œil]]'', or tricks that fool the eye. Regardless, the public's acceptance increased, and op art images were used in a number of commercial contexts. One of [[Brian de Palma]]'s early works was a documentary film on the exhibition.<ref>{{cite video|people= [[Brian De Palma]] (director)|date=1966|title=The Responsive Eye|url=http://ubu.com/film/depalma_responsive.html|medium=Motion picture}}</ref>

== Method of operation ==

=== Black-and-white and the figure-ground relationship ===
Op art is a perceptual experience related to how vision functions. It is a dynamic visual art that stems from a discordant [[figure–ground (perception)|figure-ground]] relationship that puts the two planes—foreground and background—in a tense and contradictory juxtaposition. Artists create op art in two primary ways. The first, best known method, is to create effects through pattern and line. Often these paintings are [[black and white]], or shades of gray (''[[grisaille]]'')—as in Bridget Riley's early paintings such as ''Current'' (1964), on the cover of ''The Responsive Eye'' catalog. Here, black and white wavy lines are close to one another on the canvas surface, creating a volatile figure-ground relationship. [[Getulio Alviani]] used aluminum surfaces, which he treated to create light patterns that change as the watcher moves (vibrating texture surfaces).  Another reaction that occurs is that the lines create after-images of certain colors due to how the retina receives and processes light. As [[Goethe]] demonstrates in his treatise ''[[Theory of Colours]]'', at the edge where light and dark meet, color arises because lightness and darkness are the two central properties in the creation of color.{{Citation needed|date=October 2009}}

=== Color ===
Beginning in 1965 [[Bridget Riley]] began to produce color-based op art;<ref>{{cite book|url=https://books.google.com/books?id=JFuXfLYqQVsC&q=op+art&pg=RA1-PA147|title=After Modern Art 1945-2000|first=David|last=Hopkins|date=September 14, 2000|publisher=OUP Oxford|page=147|isbn=9780192842343|access-date=November 5, 2017|via=Google Books}}</ref> however, other artists, such as [[Julian Stanczak]] and [[Richard Anuszkiewicz]], were always interested in making color the primary focus of their work.<ref>See ''Color Function Painting: The Art of Josef Albers, Julian Stanczak, and Richard Anuszkiewicz'', Wake Forest University, reprinted 2002.</ref> [[Josef Albers]] taught these two primary practitioners of the "Color Function" school at [[Yale]] in the 1950s. Often, colorist work is dominated by the same concerns of figure-ground movement, but they have the added element of contrasting colors that produce different effects on the eye.  For instance, in Anuszkiewicz's "temple" paintings, the juxtaposition of two highly contrasting colors provokes a sense of depth in illusionistic three-dimensional space so that it appears as if the architectural shape is invading the viewer's space.

==Similarities with other art styles==
Although op art is a unique style, it has similarities with styles such as [[abstract expressionism]] ([[Color Field painting|color field painting]]). Although color field painting does not give us illusions, similarities can still be found. We can see that both of these styles are minimalist, only a few colors prevail, and no object or plot is shown. These styles can cause us emotion, since there is no clear plot, the human mind itself imagines and interprets it in its own way. Cold colors are usually associated with sadness, while warm colors are associated with joy. Also, op art and color field painting are characterized by the fact that the image is aesthetic and orderly.
