DSGN 101 Vocab Quiz

Optical

The effect of color as seen in lighting conditions other than white daylight, such as rain, sunrise, sunset, candlelight, etc.

Arbitrary

The effect of color as produced by the artist imposing feelings on an object's color. This effect abandons natural color.

Additive

The process of mixing the colors of light together.

Subtractive

The process of mixing pigments together.

Pigment Wheel

A color wheel arranged to facilitate working with subtractive color. Based on the mixing of pigments, its primary colors are red, yellow, and blue.

Process Wheel

A color wheel based on primary hues of yellow, magenta, and cyan. The wheel works with subtractive color and is used for color printing, photography, and certain types of ink manufacture.

Munsell Wheel

A color wheel with hues arranged based on after imaging. its principal (primary) colors are yellow, red, violet, blue, and green. This wheel is the basis for partitive color.

CMYK

The 4 color (cyan, magenta, yellow, black or "key") screen system used to reproduce color photographs.

Primary color

A hue that cannot be obtained by mixing. mixing primary colors forms other hues and colors.

Secondary Color

a hue resulting from the mixing of a primary hue and an adjacent primary hue. Also termed intermediate hue (Violent, orange, green).

Quarternary

The Mixture of a primary hue and a tertiary hue in visually equal proportions.

Tonality

The dominance of one hue in a composition.

tone

a hue or mixture of pure colors to which only pure gray is added.

Middle gray

a mixture of black and white that is neither more black nor white but visually equal.

saturation

the relative purity of a hue. All pure hues are fully saturated.

Chroma Strength

The degree of a difference in pure hue strength. Yellow has the greatest chroma strength.

warm hue

warm hues are usually related to red and include: yellow, yellow-orange, orange, red-orange, red, and red-violet. Red-orange is the warmest hue.

cool hue

cool hues are usually related to hue and include: yellow-green, green, blue-green, blue, blue-violet, and violet. Blue-green is the coolest hue.

atmospheric perspective

The color reactions that occur when colors are perceived from a distance. As objects become more distant from the eye, the value contrast lessens, the edges become less defined, and the hues become more neutral or dull with a bluish gray cast.

light

light source or light reflected within the composition.

kelvin

The SI base unit of temperature

monochromatic

the use of a single hue and its variations to impart color to a composition.

analogous

hues adjacent to each other on the color wheel.

complementary

hues directly across from each other on the color wheel.

opacity

the condition of lacking transparency or translucence; opaqueness.

refraction

the bending of ray of a light when it enters a different material.

afterimage

a reaction seen when the observer's brain supplies the opposite or complementary hue after the observer stares at a particular hue.

simultaneous contrast

a partitive color reaction when color is in a complementary setting.

Achromatic simultaneous contrast

simultaneous contrast that concerns itself with the interactions of black, white, and grays.

Bezold Effect

The effect that occurs when colors are changed by juxtaposing them with different colors. Also known as the spreading effect.

Local

The effect of color as seen in clear daylight.

Partitive

The process of placing colors side by side to produce different reactions.

Light Wheel

A color wheel arrangement of hues that are the result of projected colored lights. its primaries are red, green, and blue, and this wheel is the basis for additive color.

RGB

Red, green, and blue: the additive primaries used in color tv and other color display systems.

Hue

The identification or name of a color.

Broken Hue

A color that is a combination in unequal proportions of all the primaries. Also termed broken color.

Tertiary

A hue that results from the mixing of a primary hue and an adjacent secondary hue. (red orange)

Quinary

The mixture of a secondary hue and a tertiary hue in visually equal proportions.

tint

the color resulting from adding black or white to a hue.

Shade

A dull color resulting from mixing a pure hue with its complementary pigment wheel hue.

high key

primarily light tones, without dark shadows.

low key

its dominant values are black, dark brown, or dark blue.

intensity

saturation, or the degree of purity of a hue.

split-complementary

a color scheme formed from any hue and the two hues at each side of its complimentary hue.

triad

a color scheme formed by three hues that are equidistant from each other on the color wheel.

transparency

when objects overlap but are still seen in their entirety.

luminosity

the ability of a color to give a glowing impression

diffraction

the breaking up of a beam of light into a series of dark or light bands or colored spectra, after hitting an obstacle.

iridescence

the play of colors due to a change of position that results in a glittering effect.

luster

the perception that imparts the impression of subdued light.

Successive Contrast

a color interaction based on afterimaging

Optical mixing

A color phenomenon based on color fusing that occurs in an eye/brain interaction. A new color is created when colors are optically fused.
