He is known for his mathematics of the eye, theories of vision, ideas on the visual perception of space, and his color vision research.

By the early 20th century, color study had become an enormous and wide-ranging topic, positioned uncomfortably with one foot in the sciences and other in the arts.

It remained for the artists and designers of the Bauhaus to end this ambiguity.

The Bauhaus was a design group founded in 1919 by German architect Walter Gropius (1883–1969).

The Bauhaus group brought

the study of color to a level of attention not

seen since Goethe’s

challenge to Newton.

These Bauhaus master students of color and color theory approached color from new directions with intelligence, wit, and energy...

Paul Klee

Wassily Kandinsky

Johannes Itten

Josef Albers

Oskar Schlemmer

These artists and writers made the definitive break between the study of color as science and the study of

color as art and aesthetics.

Johannes Itten(1888–1967)

followed Goethe in exploring color as a

series of contrast systems and opposing

forces.

He theorized seven contrasts of color based on perceptions alone:

Contrast of:Contrast of:

saturation

hue

value

warm & cool contrast

complementary contrast

simultaneous contrast

extension (area)

saturation

hue

value

warm & cool contrast

complementary contrast

simultaneous contrast

extension (area)

Itten codified color harmonies as a series of chords based on the complementary relationship and diagramed them

as geometric forms.

Itten’s approach, although

mathematically based, is much less rigid than many that preceded it.

Itten’s focus was as much on individual

perception as on mathematical relationships.

His major work is entitled, The Art of Color

Color-order systems were the first concern of theorists because a formal system establishes a structured field in

which to search for laws of color harmony.

The primary focus of that search was on the relationship between hues. Value and saturation took a back seat to hue.

Among all the major figures in color study, there was agreement that balance between complementary colors

was the first principle of color harmony.

The ancient ideal of mathematical balance was so much a part of the search for laws of harmony that hues were frequently associated with numbers or geometric forms.

Arthur Schopenhauer (1788–1860) theorized

that equal light-reflectance in spectrum

colors is inherently harmonious.

Schopenhauer’s Circle of Color Harmony is made up of unequal arcs. Each complementary pair is meant to be equal in light-reflectance to each of the other two pairs.

Every color is assigned a number representing its light-reflectance (or value) in relation to the others.

The total of all the numbers added together is 36, or 360 degrees, a full circle.

Schopenhauer’s theory can be deceptive;a large area of violet does not necessarily reflect

the same amount of light as a smaller area of yellow.

But we do sense value differences between pure colors.

Schopenhauer’s theory can be illustrated as striped tee shirts. In order for each shirt to be harmonious, the

complementary pairs must have different ratios: 1 to 1, 1 to 2, and 1 to 3.

In Itten’s quest for color harmony, he

superimposed geometric forms

(squares, rectangles, triangles, and

hexagons) over the artists’ spectrum to

demonstrate what he called “harmonious

chords.”

Each color chord illustrates

complementary colors in some measurable

proportion.

The geometric points are called the “notes” and no “chord” strays

from the complementary

relationship.

The person who made the final break with the color-order tradition was Josef Albers (1888–1976), a colleague of Itten’s who also taught at the Bauhaus school.

Albers fled Nazi Germany in the early 1930’s with his wife,

the weaver Anni Albers.

They taught first at the Black Mountain School in North Carolina and later at Yale.

Albers became the most influential name in color theory in the United States.

However, his 1963 book Interaction of Colors contained nothing like the usual charts or systems.

Albers taught that true understanding of color comes from an intuitive approach to studio exercises.

He stressed the instability and relativity of perceived colors and the power of visual training.

At the same time, he taught that even within this unstable field, there are effects that can be predicted and controlled.

In Interaction of Colors, Albers casually discounts the generations of theory that preceded him.

“This book...reverses this order and places practice before theory, which is, after all, the conclusion of practice,” he wrote.

Albers was not the first to recognize that the visual experience, more than conscious choice, determines how we perceive colors, but he was the first to assert the primacy of the visual experience over structure or intellectual considerations.

For Albers, the visual experience,

not theory, was paramount.

The late 20th century saw the focus of color study move from philosophical inquiry to a greater interest in

psychological and motivational effects of colors.

There is an entire industry, for example, that is devoted to determining current and future consumer preferences

in colors and color combinations.

At the same time, color theorists continue to search for absolutes.

There is an enduring assumption–or perhaps, a hope–that those elusive,

timeless, and absolute laws for pleasing combinations of colors really do exist and simply await discovery.
