3D Design Chapter 9

Question 1

refracted light

Answer 1

The bands of color seen when white light is passed through a prism.

Question 2

visible spectrum

Answer 2

The humanly perceptible bands of colored light created when white light passes through a prism.

Question 3

reflected light

Answer 3

The light waves that bounce back to our eye from a surface rather than being absorbed into it. These reflected waves determine what we call the “color” of the object.

Question 4

pigments

Answer 4

A powder that is the coloring ingredient for pain or other color media.

Question 5

subtractive color mixing

Answer 5

Mixing of pigments, producing a slightly darker value since each pigment subtracts its energy from the light reflected by the mixture.

Question 6

tint

Answer 6

A very light value of a hue.

Question 7

shade

Answer 7

A dark value of a hue.

Question 8

additive color mixing

Answer 8

Mixtures of light to create colors, called “additive” since each colored light ads its energy to the mixture, raising its value slightly.

Question 9

optical color mixture

Answer 9

Colors mixed visually, as when hues are closely juxtaposed in apace or when transparent layers of different colors are overlaid.

Question 10

hue

Answer 10

The characteristic of color identified by color names, such as red and blue. It corresponds to a particular wavelength within the spectrum of visible light.

Question 11

color wheel

Answer 11

A two-dimensional circular model of relationships among hues.

Question 12

primary colors

Answer 12

In color theory, those basic hues from which all other hues can be mixed. Different color theories suggest different primaries. In traditional color theory about pigment mixtures, the primary colors are red, yellow, and blue.

Question 13

secondary colors

Answer 13

In color theory, the hues created by mixing two primary colors together.

Question 14

tertiaries colors

Answer 14

In color theory, the hues created when a primary and a secondary color are mixed.

Question 15

saturation (chroma or intensity)

Answer 15

A measure of the relative purity and brightness or grayness of a color; also called “chroma” or “intensity.”

Question 16

complementary colors

Answer 16

Hues that are opposite each other on a color wheel. When mixed, they gray or neutralize each other; when juxtaposed, they intensify each other.

Question 17

neutrals

Answer 17

Colors of very low saturation, approaching grays.

Question 18

value

Answer 18

Degree of lightness or darkness.

Question 19

Munsell’s color system

Answer 19

A three-dimensional model which can be used as an instrument of measuring and naming colors.

Question 20

simultaneous contrast

Answer 20

The principle that the juxtaposition of two colors exaggerates their differences and reduces their similarities.

Question 21

local color

Answer 21

The natural color of an object.

Question 22

encaustic

Answer 22

A method of painting with pigment-bearing hot wax.

Question 23

polychromed

Answer 23

Multicolored.

Question 24

warm colors

Answer 24

Red, orange, and yellow hues.

Question 25

cool colors

Answer 25

Hues in the green and blue range.

Question 26

atmospheric perspective

Answer 26

Things seen at a distance have less value contrast and less distinct edges than things seen nearby.

Question 27

monochromatic

Answer 27

A color scheme using closely related colors derived from a single hue but perhaps varying in value and saturation.

Question 28

analogous colors

Answer 28

Hues lying next to each other on a color wheel, sometimes used together in color schemes.

Question 29

double-complementary

Answer 29

Two adjacent hues and their complements.

Question 30

split-complementary

Answer 30

One hue plus the hues on either side of its complement.

Question 31

triad

Answer 31

Three hues equidistant from each other on the color wheel.

Question 32

tetrad

Answer 32

Any four hues that are equidistant on the color wheel.
