Chapter Two: The Element of Color

Additive: created using beams of light.

Subtractive: white light is reflected off a pigmented or dyed

surface.

Process (CMYK): used in print and mass production

(transparent).

Analogous: adjacent on a color wheel.

Monochromatic: variations in a single hue.

Complementary: opposites on a color wheel.

Intensity/Saturation: the purity, or chroma of a color.

Simultaneous Contrast: optical alteration from surrounding

color(s).

Tone: hue mixed with gray or a complimentary color. 2

Color Physics

Color Physics: the art and science of color interaction and effects.

Additive and Subtractive Color:o Additive (RGB)o Subtractive (Red, yellow, blue)o Process (CMYK)o Color and Light

Color attracts attention. It is both the most elusive and complex design element. Color physics involves the study of wavelengths in order to measure and classify color, the molecular structure of dyes and pigments, the effects of color and light on our eyes and brain, and the expressive effects of color on our mind and spirit.When white light passes through a prism, it is refracted, and creates a wide spectrum of hues. Some wavelengths are reflected, while other wavelengths are absorbed. A red surface reflects the red wavelengths while absorbing the others. All wavelengths are reflected off a white surface, while all wavelengths are absorbed by a black surface. Lighting designers, videographers, and website artists use additive color. When all wavelengths are combined, white light results. Painters, printmakers, and illustrators use subtractive color in various forms, including acrylics, oils, pastels, and inks.

Color Interaction

Simultaneous Contrast Bezold Effect

Colors are rarely seen in isolation and influence one another. Lighting also affects our perceptions. Three principles of simultaneous contrast are: light/dark contrast, complementary/neutral gray, analogous variations. The Bezold effect

demonstrates that change in a single color can alter our perception of pattern. The opponent theory is created by a visual overload at the edges of shapes. The cones, or color sensors in our eyes, can register only one color in a complimentary pair at a time. Similarly an afterimage is created when we stare at a red square for thirty seconds, then stare at a white sheet of

paper.

Defining Color

Hue: name of a color, determined by its wavelength.o Primaryo Secondaryo Tertiaryo Temperature

Physicists, painters, and philosophers have devised numerous systems to organize hues. As we see in Johann Itten’s 12-step color wheel, a combination of two adjacent primaries creates secondary colors. The mixture of a secondary color and the adjacent primary color creates a tertiary color. The three-dimensional color system provides examples of changes in color value and intensity as well as hue. Temperature refers to the heat a color generates, both physically and psychologically.

Color temperatures also create the illusion of space. Warms tend to advance, while cools tend to recede.

Color

Value: The relative lightness or darkness of a color. • Tint (adding white) • Tone (adding gray or complimentary) • Shade (adding black)

Intensity/Saturation/Chroma: The purity of a color.

Violet, blue, and green are inherently darker in value than pure yellow or orange. The primary colors are the most intense. This intensity generally diminishes when colors are mixed. Compare the effect of intensity in these paintings. Hartigan’s intensity explodes, while Gorky combined the

effects until the shapes appear to glow.

Color Schemes

• Monochromatic: Variations on a single hue.• Analogous: Adjacent colors on the color wheel. • Complementary: Opposites on the traditional color wheel.• Split Complementary: A complementary color plus two colors on either side of one of the complements.

Various theories of color harmony for each term listed above. A monochromatic color scheme offers a high level of unity, but also a potential disadvantage due to boredom. Analogous colors maintain a high degree of unity and greater variety. When complementary colors are mixed, they can lower intensity and produce a wide range of browns. When paired in a

composition, complementary colors become ideal partners. Each increases the power of the others. Violet and yellow provide the widest value range, while orange and blue provide the widest range in variations in temperature. Red and green are closest in value and create extreme agitation when placed side by side. An even wider range of possibilities is offered by

the split complementary color scheme.

Harmony and Disharmony

Triadic color schemes: Three colors equidistant on a color wheel.Chromatic grays: A gray made from a mixture of various hues. Earth colors: Made from pigments found in soil.Disharmony: Used for emotional or visual impact.

The triadic color scheme pushes the choices even further apart and is used when variety and a strong impact are essential. Chromatic grays are an alternative for a simple blend of black and white, and result in a subtle and vibrant color harmony.

Earth colors are usually warm in temperature and create a type of analogous harmony. Cultural definitions of harmony are as changeable as popular music. Designers in all fields invent new color combinations each year. Disharmony is often used

when the subject matter is disturbing or when an unusual visual approach is needed. The degree and type of harmony used must depend on the ideas behind the image and on the visual context in which an image will appear.

Composing with Color

o Illusion of spaceo Weight and balanceo Distribution and proportiono Color as emphasis

The effect of color on compositions is profound. In most cases, cool, low-intensity colors tend to recede, while warm, high-intensity colors tend to advance. Figure 2.46 visually tells the story of the boy who flew too

close to the sun, melting his wings and plunging into the ocean. The black body falls into the surrounding blue background, while a red heart seems to pull the figure upward, away from death. Six bursts of yellow

add energy to the composition and meaning to the myth. Through careful distribution, even the most disharmonious colors can work together beautifully. An even distribution of colors creates a unified and

vigorous composition. Proportional distribution is another way to harmonize seemingly incompatible colors. Graphic designers often use color to emphasize critical information in a composition. In the map of figure

2.47, red clearly locates the viewer.

Color Emotion and Expression

o Color keyso Symbolic coloro Expressive color

Colors are never emotionally neutral. A dominant color or color key can heighten psychological as well as compositional impact. Color can be used to represent reality or to heighten emotion. Color meanings vary widely from culture to culture. In

Hopi culture, colors symbolize spatial location and geographic direction. The Kachina doll represents Butterfly Maiden, a benevolent spirit. Red represents a southerly direction: white, the east or northeast: blue or green, the west. Color and value each have unique strengths. Color can increase the power of a given shape, shift compositional weight, and create a focal

point. It can enhance the illusion of space, suggest volume, and heighten emotion. Well used, color is one of the most expressive elements of art and design.
